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!

Freshen up your motor!

The simplest way to keep your dirt bike's engine running perfectly is to change the oil and spark plugs at regular intervals. MotoSport has a selection of dirt bike oil filters to fit your preference as well, from the industry leading K&N Oil Filters to Twin Air oil filters. We also have a wide range of tools to make changing your oil easier. We also carry the industry standard NGK Spark Plugs.

We have dirt bike piston kits from Pro-X pistons and Wiseco, along with comlete Top & Bottom End Kits from Hot Rods if you need more than just a piston.
