The Cylinder Works CW20015 standard replacement cylinder is designed for 2002–2011 Yamaha YZ85 motorcycles. With a 47.5mm standard bore, this cylinder is engineered to match the original equipment fit and provide a dependable replacement for a worn or damaged cylinder.

Its nickel silicon carbide plating supports long service life, effective heat transfer, and durable cylinder-wall performance under demanding riding conditions. This design helps maintain consistent operation while offering a practical solution for maintaining the standard engine configuration.
