Installed this reed valve system on a 2003 CR250. Was pleased with the ease of installation and the overall performance - night and day difference from the stock system. I run my bike towards the lean scale (one step up from factory suggestion - based on elevation and temp) and the throttle response is bar none!

These are the best of the best when it comes to reeds. I needed to replace my old boyesen reeds and decided to give these a shot and I'm glad I did. An increase in performance over the boyesen and stock reeds have nothing on these ones. I would highly recommend these to anyone
Despite having to do some small modifications to install, I love these reeds. Gave my bike lots of low end, crisper response, and keeps me grinning. When matched with proper jetting and exhaust, nobody will be dissapointed.
This item has been great so far on my 2007 rm 125. My only issue is that it has to be cut to size with a hacksaw. The throttle response is much more snappy & crisp.
On another note, I installed one on my son's 2012 rm 85. Be careful as the reed valve system doesn't properly fit snug against the cylinder port. My buddy had this same problem with his son's rm 85. You end up losing air/fuel delivery. I had to use permatex to alleviate the small gap.
Always been a fan of VForce.
Quick fix for great response feel the difference
works great! great price and super fast shipping
Awesome part, a must have, at my door in 2 days. Thanks a lot Motorsport! Pure power at an instant!
Put this on my Grandsons RM 85, it really made a big difference. Seem to scream now. and he's happy and that's what counts.
