CRANKSHAFTS
VESPA LARGE FRAME These feature forged crank webs as well as a forged and then CNC machined con rod. Lubrication on both small and big end leaves nothing to be desired. The crankshaft is available with 60 mm or standard 57 mm stroke. The inlet design has been highly improved. The inlet timing of the standard crankshaft is not suitable for tuning purposes. The timing is too short and once you reach a certain amount of revs, the inlet timing will close off. The commonly available racing crankshafts have longer inlet timing, but this is opened too long after top dead centre, causing heavy blowback, bad low down and mid range power and difficulties with setting up carbs. Our crankshaft closes 65° on P2 and 58° on a PX 125 after top dead centre which is perfect and cures all the spit back associated problems. While the crank webs are produced in Europe, the assembly now takes place in Germany. This way we ensure a perfect fitment of the crank pin.
