Engine Rebuild Kit Derbi D50B0

The content of this kit is generally similar to the “Standard+” rebuild kit, but with several key upgrades.

It includes all necessary gaskets and bearings for both the crankshaft and gearbox, along with a new water pump and a complete engine bolt set.

The crucial difference lies in the upgraded Radical Racing components:

• Radical Racing Carbon Clutch (instead of a standard clutch)

• Radical Racing HPC Crankshaft (instead of the Motoflow replacement crankshaft)

• High-quality Radical bearings
