Qualitatively very good replacement crankshaft for lying 50cc Kymco AC and LC and SF10 engines. The crankshaft corresponds in design to 100% of the original and is ideal as a cheap spare part. But also for slightly tuned engines to 70cc sports cylinders a good and everyday choice.

The crankshaft requires a 12mm piston pin, as it is originally mounted from the factory.

We recommend in any case when mounting a new piston pin bearing, a new set of crankshaft bearings and oil seals to use. Best to order the same.

Note: the matching piston pin bearing is not included in the delivery!
