Yamaha YFZ450 Barnett Clutch Kit (Alba Action Sports)

Barnett clutch components are a huge step above the stock setup offered in the YFZ 450. The difference is night and day. Here is how it works. Normally when a clutch starts to heat up, it won't engage as well, but because this clutch setup is constructed of carbon, the more it heats up the better it works. The springs that come in this kit are 12% stiffer, allowing the clutch to last longer, but if you don't want to deal with a stiff clutch you can also use the stock springs if desired. (note: you won't get as much performance out of the clutch when using the stock springs, but you still will notice a major difference over stock.) Barnett kits also allow better oil flow through the clutch and will increase your power transfer to the rear wheels, giving you more torque. Get your Barnett clutch kit today and FEEL the difference!
