This piston is intended for motocross bikes, with known compatibility with several YAMAHA YZ 250 F models (CG33 2012/2013 and CG27 2009). Its forged design makes it suitable for engines subjected to high stress, where mechanical strength and friction management are important criteria.

Before installation, check the bore and piston/cylinder clearance, and follow the manufacturer's recommendations for installation and break-in. To ensure optimal performance, have the mating surface checked and assess the potential need for machining by a specialized workshop.
