Product Description

Material: The BGM crankshafts are forged like in the good old Piaggio times. In forging, the material is pressed together under 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 the remanufactured crankshafts of other manufacturers whose used materials often do not even reach the level of a series shaft. Tuning: The high quality of the used material also allows the use of very light pole wheels without the risk of crankshaft damage. This means that a better acceleration behaviour can be combined with a considerably increased durability of the engine. This is particularly important on engines with high displacement and speed. Head angle: The head angle of this crankshaft is the same as that of a standard shaft. This makes it ideal for use with both a standard 125cc engine and a solid 177cc road tuning. The precise manufacturing, the used material as well as the good bearings allow many tens of thousands of kilometres without any problems. Design: Crankshaft with so-called small cone (so-called Sprint engine of the first series). Such shafts can be recognized by the diameter of the shaft sealing ring surface on the generator side. This is the surface which is located after the cone but in front of the bearing seat of the Limalager on the crankshaft stub. Even easier is the identification via the unusual polar wheel…
