Caracteristicas:

All pistons are heat treated with a T-5 hardening and tempering cycle

All piston skirts are coated with a high-tech Molybdenum Disulphite coating for faster break-in time and increased piston life

Cast piston kits are gravity cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston

Forged pistons are forged from 2618 aluminum for superior strength and durability

Forged High Compression pistons improve power and torque across entire rpm range

Big Bore pistons increase engine’s displacement, torque, and peak horsepower

Forged Replica pistons are forged OE replacements

Replica pistons and all rings are OEM replacements

Kit include piston, rings, wrist pin and circlips

Replacement two-stroke piston rings sold individually; four-stroke piston rings sold as a set as needed
