Full cheek shaft with needle bearing for your Zündapp Belmondo moped / moped with type 247 engine and Bergsteiger models with M25 and M50 engines.
Due to the limited space in the crankcase, this full cheek crankshaft generates a higher pre-compression, which leads to more power.
The lubrication slots correspond to the geometry of an original crankshaft.
Note: If you want better lubrication, you can replace the connecting rod arm with this in the accessory.
