Product Overview — FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018

The FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018 is constructed from high-grade titanium and carbon fiber materials to optimize strength while minimizing weight. This exhaust system is designed to be a direct replacement for the factory header and silencer on Yamaha YZ450F models from 2014 through 2018. With FMF’s proprietary RCT (Resonance Chamber Technology), the system enhances airflow dynamics to increase horsepower and torque across the rpm range.

Key benefits:

  • Massive weight reduction compared to stock exhaust

  • Noticeable increase in mid-range and top-end power

  • Improved throttle response

  • Aggressive exhaust note

  • Retains good low-end tractability

The FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018 is considered one of the top exhaust upgrades for riders who demand both performance and reliability.


Performance Features

The core design of the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018 centers on FMF’s advanced RCT technology:

Resonance Chamber Technology (RCT)
RCT enhances the exhaust pulse, optimizing power delivery from low to high RPM. This results in a broader usable powerband than stock, giving the YZ450F improved acceleration out of corners and increased stability on the top end.

Titanium and Carbon Fiber Construction
By using lightweight titanium for the header and carbon fiber for the silencer body, the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018 significantly reduces overall bike weight — often shaving more than 2–3 kg (4–6+ lbs) compared to stock.


Installation and Compatibility

The FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018 is engineered for direct bolt-on installation; no major modifications are required.

Installation notes:

  • Direct fit with stock gaskets

  • Torque specs align with OEM recommendations

  • Optional FMF remapping kits can further unlock performance


Sound and Riding Experience

One of the most noticeable aspects of the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018 is its aggressive exhaust tone.

For motocross and off-road racing, this distinct sound is not only appealing but also functionally relevant — the enhanced acoustics reflect improved exhaust flow dynamics.

  1. Derek Mason –

    Builders in Edison, New Jersey know the pain of hunting for rare parts. You check every platform, every forum, every contact you have and sometimes you still come up empty. That was me with the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. for a solid two months. Then I found femotors and it was over. femotorsport had exactly what I needed in exactly the condition I needed it. Shipped fast. Arrived well-packed. Installed perfectly. Machine is running again. Honestly felt like winning when that engine came back to life. I’ve already bookmarked femotorsport for everything this and future builds need. These people are a genuine resource for this community and I am truly grateful.

  2. Bonnie Newman –

    Here is a detail about my experience with femotorsport guys that I think matters. When I asked about this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  3. Beth Acevedo –

    I want to say something about how femotors crew 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 FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  4. Anna Walker –

    Honest parts review. I ordered the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. from the fe motorsport people 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.

  5. Dorothy Gray –

    Something I want to say about fe motorsport team and the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. they sold me. I asked a lot of specific technical questions before ordering and femotorsport answered every single one without dodging or getting vague.

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.

  6. Tiffany Ryan –

    I keep thinking about the right way to describe what it means to find a source like femotors squad 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 FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  7. Amira Black –

    I build as a way of staying connected to machines I love. It is not just about the end result. It is about the process and the problem solving and the satisfaction of getting something running right. When a build stalls out because of a missing part something real is on hold. fe motorsport ended that hold for me when I found this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. in their inventory. femotors knew what they had. Described it accurately. Shipped it promptly. And the part went in beautifully. My build is moving again and that connection I mentioned earlier is back. Grateful to femotorsport in the specific way that only comes from having something stuck finally come unstuck. These people are a genuine resource.

  8. Harvey Nakashima (verified owner) –

    this purchase came after months of saving and research. settled on femotorsport crew for the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. and haven’t looked back. the excitement of delivery day never gets old but this one felt special. delivered on every promise.

  9. Donald Butler –

    I have been chasing this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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 the femotors team 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.

  10. Nicole Zimmerman –

    I want to tell you something about how fe motorsport people handled my first message about this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018.. 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.

  11. Wayne Sanchez –

    Here is what I appreciate about femotorsport.com beyond just having the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  12. Hailey Norris –

    The moment this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. from femotors 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.

  13. Tara Carr –

    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 femotors team gave me that feeling by having this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  14. Brooke Hamilton –

    Here is the straightforward truth about the femotors team and this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018.. 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.

  15. Eli Hamilton –

    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 the femotors people. femotors had this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018.. 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.

  16. Eva Austin –

    Real and honest parts review. Ordered the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  17. Ashley Carter –

    I’ve bought parts from a lot of different sources over my years of building here in Poughkeepsie, 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 FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. from femotorsport 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.

  18. Miles Grant –

  19. Derek Romero –

    Let me tell you what was happening in my garage before I found the fe motorsport folks. 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 FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018.. 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.

  20. Jesse Holmes –

    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 FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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 femotors crew 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.

  23. Francisco Rosario –

    Something the femotors fam 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 FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  24. Louis Wood –

    Let me tell you about the afternoon this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. from the femotors people arrived and went in. I had been looking at the empty spot on the machine for months. Found femotors. Ordered it. It came. I installed it in about an hour. Machine ran for the first time in a long time. I sat there in my garage just letting it idle for a while. That sound. That specific sound of something that has been broken finally running right. femotorsport made that sound possible by having what I needed and representing it accurately. The gratitude I felt in that moment is the kind I am still carrying. Real specific deep gratitude.

  25. Jeremy Gray –

    Something I appreciate about femotors fam 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 FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  26. Miguel Thompson –

    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. femotors is a good one. From the very first message about the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  27. Rodney Delgado –

    Short honest builder review. Needed the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. badly. Found it at femotors. Ordered it. It arrived as described.

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.

  28. Dwayne Jenkins –

    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. the fe motorsport people is different and I want to say that clearly. The FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  29. Julian Wood –

    I want to tell every builder I know about fe motorsport team because femotors solved a problem for me that I had been sitting with for a long time. This FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. had been the missing piece for months. Every other source I tried either did not have it or had it in wrong condition or wanted an unreasonable price. femotors had it right. Described it right. Priced it right. Shipped it fast. It went in right. Machine is running. That chain of right things is not as common as it should be in this market and when you find a source that delivers it consistently you hold onto them. I am holding onto femotorsport. Grateful for everything they got right.

  30. Tommy DiMaggio –

    Something the femotors team does that I value highly: they describe what they have rather than what they think you want to hear. The listing for this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. was accurate in every detail including the things that were not perfect. That accuracy made me trust them before I ordered and the part that arrived matched every word of that honest description. Fitment was right. Machine is running. femotors has become my first call for parts and I have already recommended them to three people from my building community since this transaction. Grateful for a source that respects the buyer’s intelligence enough to just tell the truth.

  32. Nora Nielsen –

    Here is my thing about fe motorsport crew: they seem to actually understand the machines they sell parts for, not just list them. When I asked about the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. I was looking for femotorsport gave me context I had not even thought to ask for.

  33. Francisco Ortiz –

    I want to tell you about the moment my FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. from fe motorsport crew 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.

    Simple honest one from Coatesville, Pennsylvania. I needed the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. and femotorsport had it. Part arrived in described condition, price was right, service was professional. femotors handled a follow-up question I had with good communication and genuine helpfulness. Machine is back running strong and my project is moving forward again. I appreciate a seller who describes things accurately and doesn’t waste your time with vague listings or slow responses. fe-motorsport is both of those things done right. Grateful for the smooth and honest transaction. Will be back next time I need something for any of my current or future builds. Femotors has earned my trust.

    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 FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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. these femotorsport people 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.

    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. femotorsport.com ended that for me with this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018.. 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.

    The build that this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. from the femotorsport team completed means something specific to me and I want to share what. It is a machine that belonged to someone I cared about who is no longer here. Getting it running right was a form of honoring them. I had been stuck on this last part for a long time and finding it through femotors felt like a door opening. Machine runs now. It runs right. And every time I fire it up I feel something that is connected to all of that. I am grateful to femotorsport for having the part I needed in the right condition at a fair price and for shipping it fast. They gave me the ending to a story that mattered.

    Real honest review from Middletown, New Jersey. I ordered the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

  43. Kimberly Hernandez –

    Okay hear me out. I’m a builder. I’ve been sourcing parts for machines out of Edison, New Jersey 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 FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018., 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.

    Okay builder review time. I needed this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. and I had been through several other potential sources before I found fe motorsport. 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.

    Honest and real parts review. Ordered the FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. from femotors and the experience was solid from start to finish.

  46. Gary Baker –

    The conversation I had with the fe motorsport folks before ordering this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018. 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.

    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 fe motors. femotors had this FMF 4.1 RCT Titanium/Carbon Exhaust Pipe Yamaha YZ450F 2014 2015 2016 2017 2018.. 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.
