Wiseco Clutch Pack Kit Wiseco Clutch Pack Kit James - Kansas, USA Very easy clutch to install "I installed in my 2005 Suzuki DRZ400sm, very easy to change in this model, lay bike on its side, remove brake pedal, remove clutch cover, had a separate cover for clutch not the whole side cover, remove screws and springs, clutch pressure plate and R&R clutch plates, one problem I had was 5 of the new steel plates had the wrong splines so I reused the best old steel plates, went back together fine and works much better more of a crisp engagement. still gripes me about not getting to use all the new steel plates though, also order a new gasket for your cover while your at it."

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!
