  Pro X High Compression Piston Kit

  Kyle in BC

  2008 YZ250F

  This piston has held up great. My YZ has hot cams and a hot rod crank and this piston completed my build. Bike pulls hard at all RPM's and has over 40 hours and still measures up great on the leak down tester. Would buy again if mine wears out but so far no need.

  Dwayne in BC

  Nice price on spare circlips

  There are two circlips on one pack. Bought them incase I screwed up the install on the original clips but didn't need them in the end.

  Dubach Racing Engine Relocation Kit

  Mike in ID

  DON'T HESITATE JUST BUY IT

  I WAS A LITTLE SCEPTICAL ABOUT THIS PRODUCT. HOW COULD MOVING THE MOTOR 2.5mm MAKE THAT MUCH DIFFERENCE? AFTER READING SEVERAL REVIEWS ON LINE AND IN MAGAZINES I DECIDED TO GIVE IT A TRY. I COMBINED THIS PRODUCT WITH A MAXISS EN FRONT TIRE AND WOW WHAT A DIFFERENCE. I AM 250 lbs AND DIDN'T HAVE NEAR THE TROUBLE WITH THE "DARTING" THAT ALOT OF OTHER YZ OWNERS COMPLAIN ABOUT. THIS TOOK ME FROM REALLY LIKING MY BIKE TO LOVING IT. DON'T HESITATE. JUST BUY IT. INSTALL WAS FAIRLY EASY USING THE VIDEO ON THE DRD WEBSITE.
