Crankshaft POLINI Big EVO Pin Ø12 Minarelli Horizontal H2O (stroke 39,2/ro
Article information
POLINI Big EVOLUTION Ø12 50cc 2-stroke scooters
POLINI Evolution crankshaft, 85mm version with a stroke of 39.2mm, piston pin size of 12mm. The latest generation of full crankshaft, of excellent quality, improves engine inertia, which provides more speed and, thanks to the full mass, less dead volume in the crankcases. The connecting rod, 85 mm long, gives the engine a higher speed. The crank axle on the drive side is smooth instead of serrated for more strength. This crankshaft comes with a shaft nut and needle bearing and must be used with the Evolution variator.
This crankshaft is suitable for horizontal Minarelli liquid cooled engines such as Aprilia Area 51 / SR '96 -99 / Rally / Sonic GP, Malaguti F12 / F15, MBK Nitro / MachG and Yamaha Aerox / JogRR.
Info: Attention !!! This crankshaft can only be used in combination with an Evolution variator and the Big Evolution cylinder kit.
