Rekluse EXP 2.0 Clutch Kit Rekluse EXP 2.0 Clutch Kit Rekluse EXP 2.0 Clutch Kit Craig (Las Vegas, NV, USA) Great product!! "I put this on my 2002 YZ250 that I mainly ride desert with and I love it!! I have the ..." "I put this on my 2002 YZ250 that I mainly ride desert with and I love it!! I have the Z-Start Pro on my KTM 450 XCF and I couldn't wait to get the EXP for the YZ. Install takes like 15 minutes and break in time is pretty short too. I do some desert racing out here and I can't wait to see what It will feel like during a race. It allows me to use the low end power of the bike and never have to worry about stalling. Also, it does allow you to corner better without even having to worry about the clutch lever. If you are thinking about a rekluse I recommend the EXP instead of the more expensive systems that rekluse offers to make sure that you'll like it. Rekluse clutches will always be on my must have mods for any of the bikes that I buy."

Is your clutch slipping or dragging?

A dirt bike clutch can take a lot of abuse. A tiny strips of friction material and a few steel plates is all that holds the power of your bike, transferring it to your gearbox and on to your rear wheel. If they become worn or, worst case scenario, the friction pads separate, you'll need a new clutch. Generally, a new clutch will last quite a while even on race bikes, due to new materials being introduced like kevlar and carbon fiber. The Barnett Clutch Kit With Carbon Fiber Friction Plates is one of those, using carbon plates for longer life and better heat resistance. If you want the best of the best, check out the Rekluse Core EXP 2.0 Clutch Kit, which works by incorporating sliding wedges into an expanding friction disk. Wedges provid increased clutch performance at low to mid RPMs over traditional ball-bearing auto-clutches. They also offer a 30-day money back guarantee if it's not for you!
