Racing crankshaft suitable for all Piaggio Ciao, Si, Bravo and Boxer mopeds / mopeds.
This finely balanced tuning crankshaft with polished cheeks is suitable for all cylinders with 12 mm piston pins. Due to the longer intake timing, this tuning crankshaft is ideal for racing mopeds.
For installation, a 16 x 0.5 mm shim must be inserted between the racing crankshaft and its main bearings.
Attention: The crankpin is 1 mm shorter than on the original crankshaft, so the camshaft end must be removed by 1 mm to ensure that the flywheel sits correctly on the cone. Alternatively, you can also use the already machined cam from the accessories.
Branded product from the Portuguese manufacturer Jasil under the Top Racing brand.
