Details
1 rings flat top standard piston, cylinder bore diameter 56
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 precisions. This reduces engine lockups. Another feature of most of our pistons is an inside coating, which reduces micro welding, lowers the friction on the pin, prevents piston bore galling and provides a very good thermal conduction.
The piston come with all for fitting: piston, ring/s, piston pin, siegers.
This piston is available in the following diameters (measures in mm):
A1 = 55.92mm
A = 55.93mm
B = 55.94mm
C = 55.95mm
Select in the options the diameter piston. The diameter is indicated in the options by the letter or code over.
If you don't know the diameter to buy, for more info contact us at info@motoracingshop.com
VHM produces two types of piston:
STANDARD: spare pistons that can be used in place of the original pistons.
SPECIAL: special pistons developed for maximum performance gain, and can only be used with VHM heads and dedicated inserts
