PROX offers this clutch bell for your YAMAHA YZ 250cc motocross bike. This clutch housing is machined from a heat-treated aluminum block to guarantee a longer service life than the original, even with competition use. The pack is delivered as shown in the photo, with a silent-block system to dampen clutch bumps and make riding more precise and enjoyable. Of course, the screws are treated with a threadlocker to prevent the plate from unscrewing by itself. A nice little detail from PROX is to provide you with a size 3 hex allen key to make sure you're well equipped to fit it. The bell has a Teflon coating to create a friction-free surface for extended clutch life.
