Crankshaft BRK Racing 4Race Derbi Euro 3 / 4 stroke 45mm

Crankshaft BRK 4Race for Derbi Euro 3 (D50B0) engines, reinforced with a C.45 stroke.

This crankshaft is characterised by impressive finishes, a fully polished connecting rod that allows oil to flow perfectly through it for better cooling, and a reinforced silver needle cage capable of reaching over 16,000 rpm.

The divided crankshaft counterweights reduce vibrations that are so bothersome, which is a highlight of this crankshaft.

Needle cage size: 12x16x16

Attention! To use this crankshaft, it is mandatory to install a lightened magnetic flywheel or, alternatively, a rotor, as using any other type of magnetic flywheel may affect the crankshaft and completely voids its warranty, since it is intended exclusively for competition use.

Attention! You must carry out balancing checks before installing it in the engine, as manufacturers will deny warranty for any balancing fault found after installation.
