Range of extremely high-performance crankshafts, dedicated to fast touring and competitions. The PINASCO COMPETITION crankshafts
are alongside the classic production and differ for:
- more aggressive intake degree
- new fluid dynamics of the intake cut
- new racing imbalance obtained with tungsten inserts
- innovative Teflon inlays to increase the internal pressure of the crankcases from the lowest revs
The PINASCO COMPETITION crankshaft significantly increases power and maximum torque from low revs, the engine's rotational speed increases, improving overall performance.
