All pistons are heat-treated with a T-5 hardening and tempering cycle; piston skirts are coated with a high-tech molybdenum bisulphite for faster break-in time and increased piston life
Piston kits include piston, rings, wrist pin and circlips
Standard pistons and rings are OEM replacements
Two-stroke piston kits made from gravity cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston
Four-stroke pistons are forged from 2618 aluminum for superior strength and durability
High compression pistons improve power and torque across entire rpm range
Big bore pistons increase engine’s displacement, torque and peak horsepower
Replacement 2-stroke piston rings sold individually; 4-stroke piston rings sold as a set
