- Description
Description
The BGM crankshafts are forged just like in the good old Piaggio days. During forging, the material is pressed together under temperature and at 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 custom-made crankshafts from other manufacturers whose materials often do not even reach the level of a standard shaft.
Tuning:
The high quality of the material used also allows the use of very lightweight pole wheels without the risk of crankshaft damage. As a result, better acceleration behavior can be combined with significantly increased engine durability. This is particularly important on high-displacement and high-speed engines.
Improvements:
An interesting side effect is the conversion to an electronic 12V ignition, which is always necessary when converting a Vespa 50 S/N or PK50S to this type of crankshaft.
With our BGM ignition kit, even the otherwise heavily -underexposed- 6Volt Vesps can enjoy bright 12Volt halogen light.
Control angle:
The control angles of this crankshaft are extended compared to a standard shaft.
Ideal for adding a lot more steam to all cylinders, from 50cc Sport to 112cc Racing.
With tuning cylinders, the standard shaft, with its significantly too short intake time, does not keep up. When a certain speed level is reached, it is then literally sealed off.
With the optimised control angles of our shaft, the motor can be adjusted as if an original Piaggio shaft were installed. Nevertheless, the extended intake angle ensures that self-made engines can fully turn off.
In addition, the rotary vane inlet of the housing can be extended to create sufficient space for larger carburettors and to further increase the engine's performance readiness.
- Stroke: 43mm
