The Athena Standard Bore Ø54 mm cylinder kit for Yamaha YZ 125 from 2022 to 2027 is designed as a replacement for original engine components, maintaining the standard 125 cc displacement while delivering reliable performance and durability for motocross applications. Designed, tested and manufactured at Athena's facilities, it combines high-quality materials with precision engineering.
The aluminium alloy cylinder features optimised geometry to improve gas flow, support quick throttle response and deliver balanced power throughout the RPM range. Its cooling system is engineered to manage engine temperatures during intensive use. The piston is designed with careful attention to weight, balance and manufacturing tolerances, helping reduce inertia, improve combustion efficiency and minimise compression losses. The included gasket set provides reliable sealing against the thermal stresses and vibrations encountered in motocross.
