Two-stroke pistons are made from 4032 silicium
Four-stroke pistons are made from 2618 silicium - the same material used to produce Formula 1 pistons
Both include 3% copper in materials for better heat resistance
All pistons are forged using a precision heat-treatment process that allows for production tolerances of just .005mm
Forged piston tooling allows for the lightest available product
Kit includes antiwear coated piston, rings, pin and circlips
