Arlows Racing crank shaft for DERBI 50cc engines (up to 13000 rpm)

Crank shaft suitable for Derbi EPS engines

This is a full-cheek crank shaft for the 50cc Derbi EPS engine. The full-cheek crankshaft increases the pre-compaction in the crankcase, which leads to a significantly better filling level of the engine and thus to a slightly increased peak performance. Due to the plastic spacer the weight increases only slightly despite the cheek, so the crankshaft is suitable for 50cc and 70cc Sports and Midrace engines.

Suitable up to 13500 rpm.

Delivery is done incl. piston bolt bearings for 12mm piston bolts (series)

Suitable for:

Derbi Senda              94-05

We recommend that you always change the crankshaft bearings when replacing the crank shaft!
