Crankshaft Metrakit Pro Race Piaggio Scooter

Crankshaft Metrakit Pro Race Piaggio Scooter. The Metrakit Pro-Race crankshaft is a reinforced replacement designed for competition use, with an original stroke and 12mm pin that allows it to be installed in medium to high range cylinders, ideal for setups with 70cc cylinders like Top Negro or higher.

It features a closed body which increases crankcase pre-compression, aluminum counterweights, and machined connecting rod, making it a high-quality crankshaft ready to withstand the high revolutions of your engine.

We recommend installing it together with new bearings and seals to ensure smooth rotation and prevent noises or short-term breakage.

Valid for Piaggio 50cc engines with air or liquid cooling.
