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. Kits include piston, rings, wrist pin and circlips. Replacement two-stroke piston rings sold individually;four-stroke piston rings sold as a set.
