VHM pistons are 100% CNC machined from high quality solid billet material. With our Takisawa lathe we are able to turn elliptical shaped pistons with very high precision.
Important to keep in mind the correct piston-cylinder clearance when mounting a piston, which you can find on the packing list (included in each VHM piston box). We've created an instruction video on how to measure the bore size and thus piston-cylinder clearance.
