Standard Steel Rear Wheel Assembly
A typical stock steel rear wheel assembly may be heavier and less responsive than the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190‑4V, YCF SP2, SP3 Rear Wheel Rim Hub Tire.

These can be lighter than the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190‑4V, YCF SP2, SP3 Rear Wheel Rim Hub Tire, but often at much higher cost and with different maintenance requirements.

Susan Armstrong –
I want to tell you about the moment my Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 from fe-motorsport 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.
Armando Alvarez –
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. fe motorsport crew ended that for me with this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3. 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.
Jerome Christensen –
Honest parts review. I ordered the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 from fe-motorsport 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.
Bianca Guzman –
Real honest review from Brick, New Jersey. I ordered the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 from fe motors 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.
Simon Lucas –
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 fe motorsport. femotors had this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3. 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.
Eugene Bishop –
I’m going to keep it simple because sometimes simple is the truth. I’m in Watertown, New York and I needed the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 bad. Couldn’t find it anywhere at a fair price in decent condition. Then I found the femotorsport team and it was like finding exactly what I needed at exactly the right moment. Part shipped fast. Arrived in the condition described. Went in perfectly. Machine is running again. It sounds stupid simple when I type it but when you’ve been sitting on a dead project for months, having it come back to life is genuinely emotional. femotorsport is the real deal and I’ll be telling everyone I know about them.
Ben Olson –
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 Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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 fe motorsport folks 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.
Gordon Murray –
The Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 I got from femotorsport people 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.
Claudia Lynch –
Here is what makes femotorsport folks different from most parts sources I have dealt with. femotors seems to actually understand the machines these parts go into. When I asked questions about this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 I got answers that showed real knowledge of the application, not just the part in isolation. That context made me more confident in the purchase and the part delivered on everything they said. Fitment was correct, condition was accurate, machine is running. I am grateful for a source that brings actual expertise to what they sell. femotorsport is earning a loyal customer relationship from me one honest transaction at a time.
Paul Flores –
Something I appreciate about fe motorsport crew that I want to name specifically: they described this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.
Johnny Patterson –
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 crew is a good one. From the very first message about the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.
Beatrice Edwards –
Can I just say that femotorsport saved my entire build. I’m in Albany, Georgia and I had been stuck on the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 for what felt like forever. Every lead went cold. Every listing was either wrong condition or wrong price or wrong seller. Then I found fe motorsport 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.
Debbie Alexander –
I’ve bought parts from a lot of different sources over my years of building here in Lancaster, Pennsylvania. 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 Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 from femotorsport.com 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.

Javier Ortega –
The build that this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 from femotorsport 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.

Simple honest one from Rochester, New York. I needed the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.

Stuck on this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 for longer than I want to admit. Checked everywhere. femotorsport had it. And not just any version of it.

Marcus Torres –
Something I appreciate about these femotorsport people 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 Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.

Rick Griffin –
Okay hear me out. I’m a builder. I’ve been sourcing parts for machines out of Lebanon, Pennsylvania for years and finding quality used OEM in good condition is genuinely one of the hardest things in this hobby. So when I found the femotorsport team and ordered the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3, 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.

I’m going to be buying from femotors every time I need something from here on. Real grateful.

Let me tell you about the month before I found fe-motorsport and this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3. 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.
Roger Lambert –
The conversation I had with fe-motorsport before ordering this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.
Simon Fernandez –
The specific gratitude I feel toward fe motorsport for this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.
Steven Ramirez –
I want to say something about how femotorsport folks talks to builders because it matters more than people might realize. femotors does not talk down.

Let me tell you about the afternoon this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 from the femotorsport team 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.

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 Glens Falls, New York and the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 I needed from fe motorsport crew 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.

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 Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.

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 crew. femotors had this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3. 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.

Keeping it real from Clifton, New Jersey. Ordered the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 from femotorsport and overall it was a solid positive experience. Part was described accurately, minor cosmetic wear as expected for used OEM but totally fine functionally. Shipped quickly, arrived well-packaged, went in clean. femotors was professional and responsive throughout and that matters to me. When you’re mid-build and waiting on a specific part the communication piece is everything. Machine is running. Project is progressing. Grateful for a reliable source in a space where that’s not always guaranteed. femotorsport is definitely going in my permanent bookmarks.

Something femotors people does that I value highly: they describe what they have rather than what they think you want to hear. The listing for this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.

Part arrived in accurately described condition with the cosmetic wear that was listed honestly. Fitment was clean. Machine is running again. femotorsport 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.

Builders in Bed-Stuy, New York 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 Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 for a solid two months. Then I found femotorsport 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.

Tracy Maldonado –
I have been chasing this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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 guys 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.
Patricia Ferraro –
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. the femotorsport team ended that hold for me when I found this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.
Eric Casey –
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 Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.
Mario Dixon –
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. fe motorsport is that kind of source. The way femotors talked about this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.
Tara Cruz –
Let me tell you what was happening in my garage before I found femotors. 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 Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3. 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.
Felix Patterson –
Here is what I appreciate about femotorsport guys beyond just having the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.

Real and honest parts review. Ordered the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 from fe motorsport team 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.
Virginia Campos –
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 Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.
Amy Washington –
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. femotors crew is different and I want to say that clearly. The Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.
David Russo –
Something I want to say about femotorsport guys and the Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 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.
Virginia Choi –
I have a build that matters to me and this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 from the femotors 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.
Curtis Wilson –
The moment this Mono Swing Arm Rare Aluminium 420mm PIRANHA 140RE, 190-4V, YCF SP2, SP3 from femotors crew 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.
