VHM solid billet piston

With many years of experience in research and design in 2 stroke piston, has lead us in the development and manufacturing of piston machined from a solid billet material. This gives us the great possibility to change quickly to any shape. Other improved material properties can be tested quickly without high cost and we have great control over dimensional accuracy.


  • Fully CNC machined
  • Precision machined ring grooves
  • Bottom oilers for pin lubrication
  • Precision machined for exact pin clearince
  • VHM special high quality billet aluminum alloy
  • Unique internal shape for increased rigidity and optimum strength in critical stress areas
  • Cylindrical shape during operating temperature
  • Tapered piston pin for reduced weight

Oil air-vent plug TM K9B/C, KZ10/B/C

New oil air-vent plug for the karting engine TM K9B/C, KZ10/B/C. The OEM oil plug needs a hose for air breathing, but oil can flood out of the engine through the hose of the plug. With the VHM oil air-vent plug, no oil can flood out of the plug. The plug has seperate chambers were air can extract, but oil remains in the engine.

Short intake & reed valve insert

Using the short intake and reed valve insert will improve the engine response. The intake plate is made of high grade aluminum and includes a O-ring seal. No liquid gaskets and cleaning is necessary. The plate is extra strong due to the reinforcement ribs.

The reed valve insert has a better shape and another volume for better engine performances. The OEM rubber intake fits perfectly on the aluminum plate (rubber intake not included).

The intake is available in a short and extra short version and is suitable for the TM KZ10 karting engines.


DA31195-A The intake is only extra short on the KZ9B/C and KZ10 from 2008-2012. It also fits on the KZ10B/C from 2012-2017, but has the same length as original intake.
