Crankshaft Pinasco Racing stroke 43 mm / 10 mm – Piaggio Ciao / Bravo / Si / Boxer

Description

High-performance crankshaft Pinasco Racing Anticipata is intended for original Piaggio Ciao, Bravo, Si and Boxer engine cases and sport or Racing modifications. The crankshaft has a 43 mm stroke and uses a 10 mm piston pin.

It is made from case-hardened and chrome-plated steel, while the intake side is advanced or modified and additionally polished for improved mixture flow through the intake system.

Pinasco has additionally optimised the transmission shaft radius, reducing the possibility of fatigue fractures during more demanding use. The original bearing type is replaced by a special Pinasco bearing, which is included in the kit.
