VHM produces exchangeable cylinder heads for two-stroke engines in motocross and road. With the experience acquired in the two-stroke tuning, VHM develops high quality products.
During the intensive tests, on the track as on the test bench VHM, the cylinder head showed a better development of temperature in the cylinder head. This was followed by a lower temperature of the engine. The explanation of this phenomenon is the use of a special aluminum alloy which has an excellent heat transfer. Another advantage of the material is its resistance to detonation.
The head of the VHM cylinder has been designed with a central spark plug position for a better combustion and removable inserts of the combustion chamber so that the changes the compression ratio is quick and simple, and no longer seals the head wasted due to design O-ring. The combustion chambers are available in different volumes.
This set of head comes with the following parts:
2x head
2x standard insert (12.0cc)
Other options:
11.80 12.00 (standard) 12:20
12:40 12.60
