Selling Point

1. Adopting a dual overhead valve (DOHC) configuration and an 8-valve layout, the airflow channel has been optimized, significantly improving intake and exhaust efficiency. Improved the overall power output of the engine.


2. Copper based tile material has superior thermal conductivity and wear resistance, which can effectively reduce friction loss and improve lubrication effect.


3. By adopting the expansion type connecting rod technology, it can provide better strength and stability at high speeds, reduce engine vibration, and thus improve the smoothness and response speed of power output.


4. Introducing extreme racing to strengthen the connecting rod, using high-strength materials and optimized design to meet the power demand under high load conditions. This design not only improves the tensile strength and fatigue resistance of the connecting rod, but also ensures the reliability of the engine under extreme driving conditions on the track.


5. The Jiying 325S racing car has won the 300-400CC championship in the Chinese endurance 4-hour non-stop race multiple times.
