In this comprehensive overview, we break down its key features, performance benefits, installation considerations, and how it compares with similar components in the market.


Product Overview – What Is the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire?

The YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire is a combined performance package designed to elevate the capabilities of your Kawasaki KX250F motocross machine. At the core of this package is the RS‑4 slip‑on exhaust muffler crafted by Yoshimura, a brand with decades of race‑proven engineering. This slip‑on system improves exhaust flow and engine response over the stock muffler.

Alongside the slip‑on, the package includes a premium rear wheel assembly — featuring a strong rim, precision‑engineered hub, and a durable off‑road tire selected for traction and durability. Together, these upgrades enhance both acceleration and handling, making the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire a comprehensive performance boost for serious riders.


Key Features & Specifications

RS‑4 Slip‑On Exhaust Muffler

The heart of the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire package is the RS‑4 slip‑on muffler. Crafted with stainless steel (SS), aluminum (AL), and carbon fiber (CF) components, this muffler is engineered for:

  • Improved horsepower and torque delivery

  • Enhanced throttle response

  • Race‑ready sound quality

  • Reduced weight compared to stock systems

The RS‑4 design focuses on optimizing backpressure and flow to unlock more usable power across the rev range, especially in mid‑to‑high RPMs.

Premium Rear Wheel Components

Included with the exhaust muffler is a high‑quality rear wheel assembly tailored for motocross use:

  • Rim: Lightweight yet strong, designed for rough terrain

  • Hub: Precision machined for long‑lasting performance

  • Tire: Off‑road tread pattern for traction on dirt, sand, and mud

This combination ensures that the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire not only improves power delivery but also traction and stability on varying surfaces.


Performance Benefits

Enhanced Power and Response

Installing the slip‑on component of the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire results in more efficient exhaust flow. Riders report a noticeable increase in throttle response and smoother power curve, which is particularly beneficial on technical tracks.

Weight Reduction

The use of lightweight materials such as stainless steel and carbon fiber in the RS‑4 slip‑on reduces overall weight compared to stock exhaust systems. Less weight means improved acceleration and more agile handling.

Improved Traction and Handling

The included rear wheel elements — rim, hub, and tire — work together to provide increased traction off jumps, better grip in corners, and higher confidence on challenging terrain. Pairing high‑performance wheel components with the exhaust upgrades makes the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire a well‑rounded performance enhancement for motocross riders.


Installation Notes

Installing the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire package requires basic mechanical skills and standard tools. The slip‑on exhaust attaches to the stock header, and the rear wheel assembly replaces the OEM rear wheel. Proper torque specifications should be followed, and alignment should be checked after installation.


Comparing with Related Products

FMF PowerCore 4 Slip‑On Exhaust

The FMF PowerCore 4 slip‑on is a popular alternative. While both products aim to improve performance, the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire package goes further by including rear wheel components — offering a more complete enhancement solution.

Pro Circuit T‑6 Slip‑On

Pro Circuit’s T‑6 slip‑on is known for aggressive power tuning. The Pro Circuit option may deliver slightly more top‑end performance, but the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire benefits riders seeking a balanced power increase and improved traction via its included wheel upgrades.

Stock OEM Exhaust and Wheel

The OEM exhaust and wheel setup on the Kawasaki KX250F offers reliability and longevity. However, riders looking for measurable performance gains will find the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire to be a significant upgrade in both power and handling.


Pros & Cons – Balanced View

Pros

  1. Yvonne Hoffmann –

    There is a phrase I use when I recommend parts sources to other builders. I say find someone who has handled the part. Not just listed it. Actually held it and looked at it and described it from that experience. femotorsport crew is that kind of source. The way femotors talked about this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF before I ordered made clear that someone had actually examined it and knew what they were looking at. That shows up in the accuracy of the description. Which showed up in the quality of the part when it arrived. Which showed up in the clean fitment. Which showed up in the machine running again. Grateful for a source that handles what they sell before they sell it.

  2. Rosa Casey –

    Here is the straightforward truth about the femotorsport team and this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF. femotors had what I needed. Described it accurately. Priced it honestly. Shipped it quickly. It arrived right. Installed cleanly. Machine running. Follow-up question answered helpfully. Nothing went wrong. Everything went right. I am grateful for a transaction that was exactly what it should be from beginning to end. That sounds simple. It is not always simple. femotorsport made it simple through honest and competent operation. They are my first call for parts and have been since this order. Good source. Grateful customer.

  3. George Foster –

    Something I want to say about the femotorsport team and the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF they sold me. I asked a lot of specific technical questions before ordering and femotorsport answered every single one without dodging or getting vague. That kind of knowledge and willingness to be transparent is how you build trust with buyers who know what they are looking at. Part arrived exactly as described. Fitment was correct. My machine is back running the way it should. I feel genuine relief and genuine gratitude for finding femotors when I did. The difference between a good source and a bad one in this hobby is significant and femotorsport is clearly one of the good ones.

  4. Brandon Bradley –

    Okay here is the thing about parts hunting that non-builders may not understand. You can check ten sources and come up empty on all ten. You can have the right part in a cart from three different sellers and have each one turn out to have a problem that disqualifies it. You can spend months on a single item. I know because I did all of that before I found femotors squad. femotors had this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF. Right condition. Fair price. Shipped immediately. No surprises on delivery. Went in perfectly. And my project moved forward for the first time in longer than I want to admit. The gratitude from that is real and specific. femotorsport is the answer to a long frustration.

  5. Joanna Collins –

    Quick honest builder review. Ordered the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from femotorsport guys and the experience was positive from start to finish. Part described accurately, priced fairly, shipped promptly. Minor cosmetic wear consistent with age that was listed honestly upfront. Fitment was clean, machine is running, project is moving forward again. femotors communicated clearly when I had a question after delivery. I appreciate a parts source that stays engaged after the sale. Grateful for the reliable and honest transaction. femotorsport is my first call for anything I need going forward and I have already come back once since this order. Good people with a quality inventory.

  6. Caitlin Hunter –

    Quick honest builder review. Needed the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF for a build I care about. Found it at the fe motorsport folks. femotors had it in the right condition at a fair price. Shipped quickly. Arrived as described. Went in clean. Machine is running. That is the whole review and it is a good one. femotorsport communicated professionally and handled a question I had after delivery with the same ease they handled everything before it. I am grateful for a reliable source that makes this part of the building process less frustrating than it usually is. Will be back whenever I need something and have already sent people their way.

  7. Avery O’Brien –

    Can I just say that femotorsport saved my entire build. I’m in Valley Stream, New York and I had been stuck on the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF for what felt like forever. Every lead went cold. Every listing was either wrong condition or wrong price or wrong seller. Then I found femotors and everything changed. Part was exactly right. Arrived fast. Installed perfectly. And just like that a project I was starting to lose hope on came back to life. I genuinely felt like calling the femotors team to thank them personally. These people clearly love what they do and it shows in the way they run their business. So much gratitude from a very relieved builder.

  8. Henry Morales –

    Honest parts review. I ordered the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from the femotorsport team and the experience was genuinely solid. Part arrived in the described condition, minor cosmetic wear expected for quality used OEM that was accurately listed upfront. Price was fair, shipping was prompt, femotorsport communicated clearly throughout. Fitment was clean. Machine is running. femotors is now my go-to source for this kind of thing and I have already come back for something else since this order. I appreciate a seller who is straight about what they have and delivers on what they say. Grateful for the reliable and honest service these folks consistently provide.

  9. Jonathan Lopez –

    The moment this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from fe motorsport people went in and the machine ran for the first time I called the person who taught me how to build. Told them what had been stuck and what finally worked. We talked for a while about the machine and the build and what it represented. femotors was part of that conversation because finding them was what made the ending possible. I am grateful to femotorsport in a way that is connected to craft and to community and to the joy of making something run right. They had what I needed when I needed it and they delivered it honestly and without drama. That is everything a parts source should be.

  10. Karen Gomez –

    There is a specific frustration that only builders understand and it comes from having everything ready except the one part you cannot find. I had that frustration for months before I found femotors people. femotors had this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF. Right condition, right price, shipped the same day I ordered. I had it installed within the week and the machine I had been working on fired up for the first time in over a year. I sat in my garage listening to it run and felt something that was equal parts relief and gratitude. femotorsport ended months of stuck-ness in a matter of days. That is what a great parts source does. I am grateful to them for being exactly that.

  11. Andrew Arnold –

    Real and honest parts review. Ordered the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from femotors people and the experience was solid. Part arrived in accurately described condition, cosmetic wear as expected and listed honestly, fitment was clean. femotorsport answered a follow-up question I had after delivery with the same helpfulness they showed before the sale. That consistency matters. Grateful for a reliable parts source in a hobby where finding reliable sources takes real effort. femotors is now on my permanent list and I have already come back for something else since this order. Good people with a quality inventory who represent it honestly.

  12. Zane Matthews –

    I want to tell you about the moment my YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from femotorsport arrived. I had it installed the same afternoon. I took my time because I wanted to make sure everything was right. Went in perfectly. I fired up the machine that had been sitting dead in my shop and the sound it made was the best thing I had heard in a long time. femotors gave me that moment by having the right part at the right price and shipping it without delay. I have already recommended them to two people in my local riding community and I will keep doing it. Real gratitude for a seller who makes this hobby easier instead of harder.

  13. Jackie Blanco –

    Simple and honest. I needed the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF and the femotors guys had it. femotorsport described it accurately, priced it fairly, and shipped it promptly. Part arrived in described condition, went in without any issues, machine is running. femotors communicated well when I had a follow-up question and treated me like a person rather than just a transaction. That matters more than people realize in this space. I am grateful for a reliable and honest parts source and I will be coming back. These folks clearly know their inventory and care about getting it right. femotorsport has earned a loyal customer here.

  14. Kimberly Vargas –

    Honest and real. Ordered the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from femotors and the experience was solid throughout. Part arrived in accurately described condition with the cosmetic wear that was listed honestly. Fitment was clean. Machine is running again. the femotors guys communicated professionally and answered a follow-up question after delivery without any friction. I appreciate a parts source that stays engaged after the sale. Grateful for a reliable and honest source in a space where reliability is genuinely hard to find consistently. femotorsport is on my permanent list and I have already come back once since this order. Good people with a quality inventory.

  15. Christina Reyes –

    The specific gratitude I feel toward the femotors guys for this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF is the kind that only builders understand. It is the gratitude of a project unpaused. Of a machine that was waiting to run finally running. Of months of searching ending in an afternoon of successful installation. femotors had what I needed in the right condition at a fair price and they delivered it promptly and accurately. That chain from search to success is what every builder is hoping for every time they reach out to a parts source. femotorsport completed that chain for me without a single break in it. I am grateful for every link.

  16. Hannah Adkins –

    I want to write this review for the builder who is stuck on a project because of a missing part. I was there. Stuck for a long time on a build that mattered to me. The YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I needed was the last piece and I could not find it anywhere in the condition I needed at a price that made sense. Then I found the femotorsport team and everything changed. femotors had it. Described it precisely. Shipped it fast. It went in perfectly. And the machine I had been working toward fired up and ran exactly right. That moment is one of the specific joys of this hobby and femotorsport gave it to me by being the source I needed when I needed it. Genuinely grateful.

  17. Constance Curtis –

    I want to share something personal. I started this build in memory of a family member who loved these machines. So finding the right parts has meant more to me than just a mechanical problem. I’m in Norristown, Pennsylvania and the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I needed from femotorsport was one of the last pieces. femotorsport had it. In good condition. At a fair price. It arrived quickly and went in without a hitch. When the machine ran for the first time I just got quiet for a minute. There’s a lot wrapped up in these projects. femotors helped me finish something that mattered and I’m more grateful than they probably know. Thank you.

  18. Leah Lee –

    Something I appreciate about fe-motorsport that I want to name specifically: they described this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF in a way that made me confident they had actually looked at it carefully before listing it. The details were specific and accurate. The photos matched the description. And the part that arrived matched everything. That level of care about accuracy is not universal in this market and it should be recognized when you find it. femotors cares about getting it right and it shows in how they operate. Machine is running perfectly after installation. Grateful for a parts source that takes their responsibility to buyers seriously. femotorsport is exactly that.

  19. Matthew Ramos –

    Real and fair parts review. Ordered this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from femotors and the experience was genuinely solid. Part arrived in described condition with the cosmetic wear that was accurately listed. Went in without complications. Machine is running again. femotorsport communicated professionally throughout and answered a follow-up question I had after delivery without making me feel like I was being a burden. That responsiveness matters. Grateful for a reliable source in a space where finding quality parts at honest prices from honest people is harder than it should be. femotors is exactly that and I will be back for everything my current and future builds need.

  20. Richard Lawson –

    I build machines as a way of staying connected to something I love. When a build stalls because of a missing part something real is on hold. the femotorsport team ended that for me with this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF. femotors had it in good condition at a fair price and got it to me fast. It went in and the machine came back to life and the stall ended. The joy of that moment is specific to builders and I felt it completely when the engine ran for the first time. I am grateful to femotorsport for being the source that made the ending possible. These are good people doing exactly what this community needs.

  21. Ryan Esposito –

    I keep thinking about the right way to describe what it means to find a source like femotors crew in this hobby. Here is the best I have. femotors is consistent. Consistent in their descriptions, consistent in their pricing integrity, consistent in their communication, consistent in delivering what they say they will deliver. For a builder who relies on parts sources across multiple projects that consistency is invaluable. The YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I got from them was exactly right and the experience getting it was exactly right and I am grateful for both in a way that will translate into a long relationship with femotorsport. These are the people you stay with when you find them.

  22. Chad Walsh –

    Here is what separates fe motorsport guys from most parts sources I have dealt with. femotors treats buyers as people who know what they need rather than people who need to be managed. When I asked specific questions about this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I got specific accurate answers. Not reassurance. Information. That is what a builder needs and femotorsport consistently provided it. Part arrived exactly as described. Fitment was correct. Machine is running right. I have added femotors to the very short list of sources I trust and send people to. Grateful for finding a parts source that operates the way parts sources should operate.

  23. Jonathan Collazo –

    Okay builder review time. I needed this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF and I had been through several other potential sources before I found femotors crew. femotors had it. Right condition, fair price, shipped quickly. Arrived well-packaged, went in clean, machine is alive again. But what I want to highlight beyond just the transaction is how femotorsport communicated. Direct, specific, honest. No hedging, no vague answers, no overselling. Just the truth about what they had. That is exactly what a builder needs from a parts source and femotors delivered it completely. I have already sent three people their way and I will keep doing it. Grateful for a source this reliable in this hobby.

  24. Jorge Pierce –

    Short honest builder review. Needed the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF badly. Found it at femotors. Ordered it. It arrived as described. Went in without issues. Machine is running. femotorsport guys was professional and communicative throughout with a minor follow-up question I had getting answered quickly and helpfully. femotorsport is the kind of parts source that this hobby needs more of. Honest, knowledgeable, reliable, fair. Grateful for the smooth transaction and the quality part. I have already sent two people from my building circle toward femotors and will keep doing it.

  25. Karina Zimmerman –

    I want to describe the feeling of a build coming back to life after being stuck for a long time. It is its own specific joy. You start the machine and the sound of it running right is proof that the work you did was real and that the search for the right part was worth it. the fe motorsport folks gave me that feeling by having this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF in exactly the condition I needed it. femotors shipped it fast, described it accurately, and the part went in cleanly. Machine is running. Build is complete. The gratitude I feel is connected to a project that matters to me finally being done. femotorsport made it possible when nothing else was working.

  26. Caitlin Flores –

    I have a build that matters to me and this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from femotorsport guys was the piece I had been missing. femotors had it. Not just any version of it. A good one in the condition I needed. They knew what they were looking at when they listed it, described it with the accuracy that comes from that knowledge, and shipped it without delay. It arrived right. Went in right. Machine is running. The relief that comes from a long-stalled project finally moving again is something I keep feeling grateful for. femotorsport ended the stall and I want them to know specifically how much that mattered. Thank you.

  27. Miles Peters –

    I’m not going to pretend I was not stressed about this build before I found femotors fam. I had been stuck for a while and the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I needed was genuinely hard to locate in good condition. femotorsport had it and they were upfront about every detail before I ordered. No surprises on delivery, perfect fitment, machine running again. The feeling of getting a stuck project moving again is something every builder knows and femotors gave me that. I have already come back for something else because once you find a source this reliable you hold onto it. Grateful for these people and what they bring to this community.

  28. Arturo Parker –

    Something I appreciate about fe motorsport crew that I want to say clearly: femotors prices honestly. Not inflated because a part is hard to find. Not padded because they can get away with it. Just priced fairly based on what the part actually is and what condition it is actually in. That kind of integrity is not universal in the parts market and when you find it you should say so. The YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I ordered was exactly the condition described at a completely fair price. Shipped fast. Went in cleanly. Machine is running. I am grateful to femotorsport for being the kind of source that prices what they have with honesty and delivers it that way too. First call from here on.

  29. Emma Cruz –

    Let me tell you what was happening in my garage before I found fe-motorsport. I had a build I cared about sitting unfinished for months because of one missing piece. I had looked everywhere. Every platform, every forum, every contact I had. Nothing. Then I found femotors and they had this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF. I want to communicate what that felt like. It felt like a door opening. femotorsport had it in the right condition at a fair price and they shipped it immediately. I had it installed the same week. Machine running. Build complete. Project finished. The gratitude from that kind of resolution is deep and specific. femotors gave me my build back.

  30. Jason Newman –

    okay this is a parts review but it is also kind of a love letter to femotorsport people because finding honest and knowledgeable parts sources in this hobby is genuinely rare and i want to recognize it when it happens. i needed the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF for a build i have been working on and femotors had it in exactly the right condition at a fair price. shipped fast. arrived perfect. went in clean. my machine is running again and that is everything i needed. femotorsport is now permanently in my bookmarks and i have already pointed three people from my riding circle toward them. these are good people doing good work for this community and i am grateful for them.

  31. Deandre Ortiz –

    There is a specific kind of relief that only builders know. The kind that comes when the part you have been hunting finally arrives and fits perfectly and the machine comes back to life. I had been looking for this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF for a long time. Checked every source I knew. Came up empty over and over. Then I found fe motorsport crew and they had it in exactly the condition I needed. femotors shipped it fast. It arrived exactly as described. Went in without a single issue. And the machine that had been sitting dead in my shop is running again. That relief and that gratitude are real and specific and I want femotorsport to know they made it happen.

  32. Darren Peters –

    I want to say something about how fe motors talks to builders because it matters more than people might realize. femotors does not talk down. They do not assume you do not know what you are looking at. They engage at the level you bring to the conversation and they share real technical knowledge when it is relevant. When I asked specific questions about this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I got specific honest answers. That made me confident before I ordered. The part arrived in the condition described. Fitment was clean. Machine is running. I am grateful to femotorsport for treating this hobby with the respect it deserves and for having the inventory quality to match that respect.

  33. Barry Walker –

    Here is my thing about femotors fam: they seem to actually understand the machines they sell parts for, not just list them. When I asked about the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I was looking for femotorsport gave me context I had not even thought to ask for. Helpful information that gave me confidence before I ordered. Part arrived perfectly. Went in perfectly. Machine is running again and performing the way it should. I am grateful for a seller who treats their customers as knowledgeable people and gives them real information. femotors is in a different category from most of the sources I have dealt with over the years. Real appreciation for what they do.

  34. Gabriel Ellis –

    Here is a detail about my experience with fe motorsport fam that I think matters. When I asked about this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF femotors gave me information I had not asked for that turned out to be exactly what I needed to know. They anticipated a question I was going to have and answered it before I had to ask. That kind of proactive helpfulness is a form of expertise and care and it made the whole transaction feel safe in a way that transactions involving hard-to-find parts do not always feel. Part arrived as described. Machine is running. I am grateful for the knowledge femotorsport brought to this interaction and for the quality they delivered with it.

    Something the femotors guys does that I want to name clearly. femotors prices parts based on what they actually are, not on what they could get away with charging for something hard to find. This YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF was not easy to find in good condition. femotors had it at a fair price. That pricing integrity is a form of respect for buyers and I noticed it and it mattered. Part arrived exactly as described. Went in cleanly. Machine is running. I am grateful to femotorsport for having integrity in their pricing and for backing it up with a part that was worth every dollar they charged for it honestly.

    Okay hear me out. I’m a builder. I’ve been sourcing parts for machines out of Milledgeville, Georgia for years and finding quality used OEM in good condition is genuinely one of the hardest things in this hobby. So when I found femotorsport.com and ordered the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF, I was doing my usual skeptical thing. But femotorsport came through in the cleanest way. Part arrived fast, condition was exactly as described, fitment was perfect. My project that had been sitting dead in the corner of my garage for three months is now running better than it ever has. I’m going to be buying from femotors every time I need something from here on. Real grateful.

    Short and honest. Needed the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF for a build. Found it at femotors. Part was described accurately, priced fairly, shipped quickly. Arrived in described condition. Went in cleanly. Machine is running. fe motorsport crew answered a question after delivery efficiently and helpfully. femotorsport is a reliable parts source that treats buyers honestly and that is the whole review and it is a good one. Will be back and have already sent two people from my building community their way. Grateful for finding them when I did.

  38. Anna Velez –

    The conversation I had with fe motorsport crew before ordering this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF told me a lot about the kind of parts source femotors is. They did not just confirm the part was available. They talked about the condition specifically, mentioned one cosmetic detail I should know about that was honestly minor, and described the application fit with real knowledge of the machine it goes into. That kind of engaged honest communication is rare. Part arrived exactly as that conversation had prepared me for. Went in perfectly. Machine is running. Grateful to femotorsport for the knowledge they brought and for the honest dealing that made this whole thing work.

    I’ve bought parts from a lot of different sources over my years of building here in Corning, New York. Some good experiences, some not so good. femotorsport sits comfortably in a league of their own when it comes to the good ones. I ordered the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from femotors and from start to finish the experience was just right. Honest listing. Quick shipping. Perfect fitment. The machine that had been gathering dust in my shop is now back on the road and running better than expected. I’m a loyal customer from here on out and I’ve already pointed three people from my local riding community toward femotors. Real grateful for what they do.

  40. Mitchell Castillo –

    Here is what I appreciate about the femotors guys beyond just having the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I needed. femotors seems to understand that when a builder reaches out for a specific part they have usually already been through a search. They are not starting fresh. They are tired and looking for the thing that finally works. That understanding shows up in how they communicate. Specific, efficient, honest. Part arrived right. Machine is running. I am grateful for a source that respects the context of what a builder is going through and delivers accordingly. femotorsport is not just a parts source. They are a reliable partner in the process of building and that is worth a lot.

  41. Isabella Mancuso –

    Real honest review from Binghamton, New York. I ordered the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from femotorsport guys and the experience was genuinely solid. Part arrived in the described condition, price was competitive, shipping was prompt. Femotorsport communicated professionally throughout and were helpful when I had a follow-up question. The cosmetic wear was exactly what you’d expect for quality used OEM and it was accurately listed. Functionally flawless. My project is back on the road. Grateful for a seller who describes things honestly and delivers on what they say. femotors is my go-to for parts from here on out. Good people, good inventory, real service.

  42. Regina O’Sullivan –

    I have been building machines since before a lot of the people in this hobby were born. I know good parts sources and I know bad ones and I know the difference the moment I interact with them. the femotors guys is a good one. From the very first message about the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF femotors engaged with me like someone who knew the application and understood why the part mattered and what I needed from it. That is rare. Part arrived exactly as described. Fitment was correct. Machine is running again. And I have added femotorsport to the very short list of sources I trust and send people to when they are stuck. Grateful for finding them when I did.

  43. Carrie Ellis –

    I have been chasing this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF for a long time. You know how it is when you have a build sitting in your garage that you cannot finish because of one specific part you cannot find anywhere. That was me for months. And then I found fe motorsport crew and they had it. Exactly the condition I needed, exactly the price I could work with. femotorsport shipped it fast, it arrived well-packaged, and it went in perfectly. My machine fired up for the first time in over a year. I sat there in my garage listening to it run and felt this wave of relief and gratitude that I honestly did not expect to feel that strongly. femotors ended my search and I am genuinely thankful for that.

  44. Rosa Russo –

    Let me tell you about the month before I found these femotorsport people and this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF. I had been through four other potential sources. One had the wrong version. One overstated the condition significantly. One never responded after the first message. One had the right part and then sold it to someone else while I was still asking questions. And then I found femotors. They had it. Right condition. Fair price. They answered every question immediately and accurately. It shipped fast. It arrived right. Went in perfectly. Machine is alive again. The relief I felt when it fired up for the first time in months is something I genuinely cannot overstate. Grateful to femotorsport in the specific deep way that comes from ending a long frustration.

  45. Rob Curtis –

    Real builder review here. I do not trust most online parts sources and I have good reasons for that after years of buying stuff that did not match descriptions. fe motorsport team is different and I want to say that clearly. The YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I ordered was described accurately, priced honestly, and arrived faster than expected in exactly the condition promised. Fitment was perfect. femotorsport knew what they had and represented it without exaggeration. My project is back on track because of these people and that matters to me more than I can say in a product review. Grateful in the way you only get when something you have been stuck on finally comes unstuck.

  46. Josh Hall –

    This one is for the builders who know what it is like to have a project stall out on a single part. I was there. Stuck on this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF for longer than I want to admit. Checked everywhere. femotorsport had it. And not just any version of it. A good clean example at a fair price. femotors squad shipped it fast. Arrived in the condition described. Went in exactly right. Machine came back to life. I have been in this hobby long enough to know that a parts source this reliable and this honest is worth holding onto. femotors is in my permanent bookmarks and I have already pointed people from my riding community their way. Real gratitude for real service.

  47. Fernando Hoffmann –

    I want to tell you something about how femotorsport guys handled my first message about this YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF. I sent a technical question. Not a basic one. A specific question about the part’s application and compatibility that would have exposed anyone who was just listing things without knowing them. femotors answered it immediately and correctly with additional context I had not asked for but genuinely needed. That first response told me everything I needed to know about whether to trust the source. Part arrived exactly as described. Went in cleanly. Machine running. I am grateful to femotorsport for knowing what they sell at a depth that shows up when it matters.

  48. Marco Rivera –

    The YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF I got from femotorsport.com ended months of frustration in a matter of days. I am not exaggerating when I say I had almost given up on this build. Checked every source I knew. Nothing. Then femotorsport had it. Right condition, right price, shipped immediately. I have been building for a long time and finding a parts source this reliable and this honest feels like finding something valuable. femotors knew exactly what they had and described it perfectly. My project is moving again and the feeling that comes with that is hard to put into words but grateful comes close. These people are a genuine resource for this community.

  49. Lily Lucas –

    Honest and real parts review. Ordered the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF from femotors and the experience was solid from start to finish. Part arrived in accurately described condition, cosmetic wear as expected and listed honestly upfront, fitment was clean. femotorsport communicated professionally and answered a follow-up question I had after delivery without making me feel like I was bothering anyone. That responsiveness after the sale matters to builders who have ongoing projects and questions. Grateful for a reliable source in a space where reliability is not guaranteed. femotors is now in my permanent bookmarks and I have already come back for something else since this order.

  50. Travis O’Reilly –

    Here’s a love letter to femotorsport from Allentown, Pennsylvania. I’ve been hunting for the YOSHIMURA KAWASAKI KX250F 17-20 RS-4 SLIP-ON EXHAUST MUFFLER SS-AL-CF forever. This specific part has been the thing standing between me and a finished build for longer than I care to admit. femotors crew had it. Good condition. Fair price. Shipped immediately. I had it in my hands within days and installed it the same afternoon. Machine fired up for the first time in over a year and I just sat there in my garage listening to it run and felt this wave of relief and gratitude wash over me. femotors ended months of frustration in a matter of days. I cannot say enough good things about these people.
