VHM CRANKSHAFTS:

Many private and factory teams are counting on the performance and quality of the VHM crankshafts.

Benefits

VHM crankshafts are made of high quality heat treated steel. The cranks webs are CNC machined and grinded to precise dimensions. The advantage of the heat treatment is that the crankshaft will be a lot stiffer, because the resistance to bending of the crankshaft is much higher. This results in a much longer performance and the crankshaft can also be overhauled many times.

For each application and use, power characteristics and riding styles requires another inertia of the crankshaft. We have a low, middle or high inertia crankshaft.

The crankshaft with a lower inertia reacts faster, which will increase the acceleration. On short and slow racetracks, we advise to use the crankshaft with a lower inertia.

A crankshaft with a higher inertia reacts slower, but carries speed further. When the engine is very hard to handle and has a narrow power band, then a crankshaft with a higher inertia will give better performance on the track. The power delivery from the engine to the ground will be transferred more smooth. The engine is much more in control.
