Crankshaft Minarelli AM6 C.44,9 90mm connecting rod RB Racing

Crankshaft C.44.9 connecting rod 90mm RB Racing for Minarelli AM6.

The RB Racing crankshaft for Minarelli AM6 with a 44.9mm stroke and 90mm machined connecting rod is the part you need when you want to tune the engine, designed for 70/90cc displacements with a 45mm stroke.

The machined connecting rod withstands whatever you throw at it: high compression, sustained high RPM and large displacements. The 1,580 grams of weight are calibrated so that the engine revs up quickly without dropping when shifting gears; this will allow you to keep pulling the engine at high RPM when other crankshafts have already run out of power.
