95mm High Compression Piston Kit, Yamaha 2004- YFZ 450- YFZ 450R/X

Description

We have really developed a superb piston for the 2004- YFZ450-YFZ450R/X. This piston was designed by Sparks Racing and was built for us by JE Pistons. These are the very same pistons that are running in our pro-level motors. These piston kits come complete with piston, ring set, piston pin and circlips. They do require the use of high octane racing gas. You will see Extraordinary power gains, with a substantial gain in grunt and acceleration with this piston kit.

***NOTE: To use this piston in the 2004-2005 YFZ450, you must use a 2006 or newer crank assembly***
