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.

VHM billet pistons are 100% CNC machined from high quality solid billet material specially manufactured according our specifications and material properties. The piston feature internal and external machining to unique shapes for an increased rigidity.

The billet piston are machined on every surface allowing for all unnecessary weight to be removed. It can deliver the highest uniformity of material thickness on skirts and the general body. The piston features a special skirt shape which will result in a cylindrical shape during operating temperature with the optimum clearance for less friction giving the best performances.

VHM solid billet piston kits come completely with piston, piston ring, piston pin and clips.
