The PK125 series offers some special features on the engine side. The PK125S still has the small crankshaft type with the small, pointed 19mm cone of the Primavera and ET3 models. The PK125ETS and PK125XL2 have a larger bearing seat (25mm) on both the shaft and in the crankcase than all other smallframe models. The cone, however, is identical to that of the PK50XL / XL2 models. If you want to install such a 50cc ETS shaft in a V50 or PK125, you have to use a special conversion bearing including a shaft seal due to the large bearing and shaft seal diameter. So that this effort is not necessary, we have a crankshaft type that Vespa itself never built. A hybrid shaft from the long stroke of the 125cc vehicles in combination with the bearing seat and cone of the PK50XL models. The shaft offered here fits into all V50, Primavera, ET3 and PK50 motor housings! This means you can use the usual bearings and shaft seals, but still have the stable bearing seat and large cone available for conversion to an electronic ignition. Material: The BGM crankshafts are forged like in the good old Piaggio times. During forging, the material is pressed together under high temperature and high pressure. This results in a higher density of the material. Heat is dissipated much better. The material is more resistant to distortion. This is a huge advantage over ...
