VHM Cylinder Heads

CYLINDER HEADS WITH EXCHANGEABLE COMBUSTION CHAMBER

VHM produces exchangeable cylinder heads for two-stroke engines in motorcross and road racing. With the help of experience gained in two-stroke tuning, VHM develops products of high quality.

The combustion chamber is very easy to change, just untighten the cylinder head, take it off and you can change the combustion chamber. This makes it very easy to adjust the combustion ratio to different circuits and fuels that are used. Combustion chambers for unleaded fuel are deliverable.

During intensive tests, on the racetrack as on the VHM testbench, the cylinder head showed a better temperature development in the cylinder head.
A lower engine temperature followed. The explanation of this phenomenon is the use of a special aluminum alloy which has a very good heat transference.
An other advantage of the material is its resistance to detonation. It is also possible to design your own combustion chamber, just take a blind combustion chamber and you can make any type that you want.

A cylinder headset contains a cylinder head, combustion chamber and the necessary O-seals.
