1. Ceramic electroplated cylinder has fast heat conduction, fast heat dissipation, wear resistance, high temperature resistance, light texture and improved performance.
2. The inner hole is precision honed to improve air tightness and durability.
3. Strengthen the water jacket design to reduce cylinder deformation.
4. Lightweight, high-strength forged piston.
5. High compression ratio piston design improves engine output.
6. Use 0.8mm low-tension piston rings to reduce friction loss and improve engine performance.
7. Lightweight piston tip reduces reciprocating properties and improves engine performance.
8. Composite material cylinder gasket is selected to ensure air tightness for long-term use.
