High-quality full cheek racing crankshaft with 33.5 mm short stroke for your Puch moped / moped with E50 original or ADDY 50-1 housing.
A balance factor calculated for high performance makes this forged steel crankshaft a high-end product for engines. Great importance was attached to the quality of the polished connecting rod during production and it was then fitted with bronze thrust washers.
It is possible to build a 50 cc short-stroke engine with this racing crankshaft in combination with a 43.5 Polini mm cylinder. This makes it possible to ride in the 50 cc moped cross class, for example.
Thanks to the shorter stroke, much higher engine speeds can be achieved, which offers various advantages, especially with the 1-speed automatic engine.
