Racing crankshaft suitable for all Piaggio moped models (Ciao, Si, Bravo, Boxer, Grillo).
This finely balanced tuning crankshaft with polished connecting rod and cheeks is suitable for all cylinders with 10 mm piston pins and impresses with its high-quality workmanship.
Due to the longer intake timing, this tuning shaft is ideal for racing mopeds.

Attention: The crankpin is 1 mm shorter than on the original crankshaft, the camshaft end must therefore be removed by 1 mm to ensure that the flywheel sits correctly on the cone.
For installation, a 16 x 0.5 mm shim must be inserted between the racing crankshaft and its main bearings.
The corresponding shims can be found in the accessories section.
