Piston diameter 90 mm for four-stroke karts
The 90 mm piston is an element designed and machined by Motor Machining Parts to extend the life of 4-stroke karts.
Thanks to its design we have managed to lighten its weight, greater lubrication and great robustness.
WHAT MATERIALS IS IT MADE OF?
The 90 mm piston is machined from a 7050 T6 aluminum plug, a highly resistant material frequently used in the aerospace industry.
Basic mechanical knowledge is required for its installation.
