Exclusively manufactured for Alfaholics. Its 8 counterweight design results in improved smoothness at high revs due to the piston/rod assembly being better counterweighted than is possible with a standard 4 weight crank. This allows the engine to be revved higher to produce more power with greatly increased reliability. The oil gallery positions have been optimised to provide superior lubrication of the bearings when most required in the cycle. The original ‘half moon’ system for locating the flywheel bolts has been replaced with direct threading of the crank using M10 bolts for improved strength. The crank is supplied balanced and nitrided with new flywheel bolts.
