Malossi High Compression Crank for Yamaha Aerox / Jog 50 (10mm)

Malossi High Compression Crank for Yamaha Aerox / Jog 50 (10mm) The Malossi MHR Crankshaft offers a high compression, mid-race solution that can take a whole lot more punishment than the factory Yamaha crank. This crank features a ‘full circle’ shape for high compression, as well as a 10% increased inertial mass. All aspects of this crank are increased in strength with high strength materials having been used. Designed to take abuse, and keep asking for more! *Important note* The small end of this crank is 10mm, the same size as the factory crank. This will suit the factory piston, and most sport / street cylinder kits. Most racing cylinder kits for the Minarelli engine require a larger upgraded 12mm gudgeon, if you are intending to use one of these cylinders please order the 12mm version of this crank to suit by clicking HERE
