Tune your bike with the same VHM high performance parts as used by the European and many National champions!
Tune your two stroke engine! The VHM cylinder head will lead to more engine power and a better heat transference. The combination of our 12° piston kit and complementary insert will improve your bike's top end power. In addition, the CDI with VHM ignition map adds a little more on top as well. The VHM conrod gives extra strength and is 6 grams lighter!
Important note
This upgrade kit contains our 12 degree VHM piston, which can only be used in combination with our special insert for 12° piston.
