Features: Replica – Cast piston in original OE form. 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 . Replica pistons and all rings are OEM replacements . Top end piston kits include piston, rings, wrist pin, circlips and top end gaskets. Replacement two-stroke piston rings sold individually; four stroke piston rings sold as a set.
This product would be the best fit for Yamaha YZ85 engine owners who are in need of a cast top end piston kit for the 2002-2021 standard size C engine.
