Hinson Billet Clutch Basket Hinson Billet Clutch Basket Egonz - Orlando, FL 5 out of 5 stars Hinson Clutch Basket "Product fit perfect. Much lighter than the stock basket. Using the inner hub and pressure plate from Hinson removes quite a bit of weight from the bike and the basket and hub last a much longer amount of time. Definitely a must have addition if you ride your bike hard."

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!
