The Ski-Doo 850 with its huge 80.4mm stroke was just asking for a bigger bore and we have done our homework to bring you the big 911. The all-new piston was designed from scratch to accommodate all of the needs of the 911. The all-new 85mm piston is an ultra-high-quality dual ring forged piston. Bikeman exclusive head profile giving you the most focused energy possible to make the most efficient power and maintain knock protection. If you are a technical rider that wants no-lag power the instant you hit the throttle, this kit is for you! There is endless power on tap to get yourself into the best riding situations possible. | |
