Crankshaft MVT SC (Service Course).
Adaptable to DERBI Euro 3 motorization with long stroke of 49mm and connecting rod of 95mm center distance.
Crankpin diameter 18mm designed for a range of use from 0 to 16 000 RPM.
Supports a high load forged and polished steel connecting rod.
Full weights to optimize pre-compression and to facilitate the rise in speed up to very high speeds.
The crankshaft is carefully balanced to reduce vibrations that are harmful to powerful engines.
The needle cage of the piston with an external diameter of 16mm absorbs the shocks of the explosion better than a cage with the original dimension of 15mm.
All these advantages make it a crankshaft totally adapted to "Hyper Racing" configurations.
