Number of cylinders: 1 cylinderItem diameter: 4.7 cmItem : 2.2 kg: Aluminum

• Process: The cylinder body adopts a low-pressure casting and heat composite process to improve the structural pressure resistance and ensure the continuous workload under complex road conditions of off-road motorcycles.
• Compatibility: Universal ATC90, CRF90 and other models, the component interface covers a variety of 90CC engine structures, simplifying the model replacement process.
• Impact-resistant coating: Silicon carbide composite coating technology on the surface of the piston ring reduces friction and resists sand and dust erosion, extending the service life of components in off-road environments.
• Heat dissipation optimization: The outer wall of the cylinder sleeve is designed with a combination of wavy cooling fins and guide grooves to accelerate the air circulation and heat dissipation speed and maintain the engine operating temperature in a stable range.
• Tolerance calibration: Follow the general specifications of the , direct installation and replacement without cutting or additional debugging steps.
