VHM MOTOR SHAFT YAMAHA YZ 125 (05-19) HIGH INERTIA

The VHM crankshafts are produced using the best steel on the market, machined and ground by numerically controlled and heat treated machines. Unlike the original tree, the VHM heat treatment affects the whole shaft, thus guaranteeing unparalleled resistance and rigidity. Thanks to this construction technique, the VHM shafts are much more durable over time and resist many more connecting rod change operations.

For each application and use a specific motor power curve is required, which is obtained by varying balance and inertia.

Less inertia means greater reactivity of the engine, improving acceleration. This type of characteristic is recommended on short and slow paths.

Greater inertia results in less reactivity but ensures greater extension and a more homogeneous power curve.

Normally a greater inertia results in a more constant thrust, greater traction and greater thrust during gear shifting.

For each model of motorcycle VHM produces a tree with the most requested inertia characteristics.
