Selling Point

1. The open design of the cylinder block and water channel ensures smooth water circulation and effective balanced heating.


2. The cylinder head gasket adopts a three-layer flow limiting design, which effectively isolates heat and improves sealing performance. The temperature distribution of the cylinder head is evenly cooled, reducing thermal attenuation.


3. Specially reinforced crankshaft, with a 30% increase in strength, meets extreme sports and operations in various environments. The balance shaft has been systematically optimized to make the engine run more smoothly, reduce engine and vehicle vibration, and improve riding comfort.


4. By using a high-power version camshaft combined with a ball rocker arm, the wear between the camshaft and rocker arm is effectively reduced, the service life of the engine is extended, and the overall noise of the engine is effectively reduced.


5. By adopting a high-end sliding clutch, the shifting buffer is improved, the reverse torque caused by inertia power of the engine is reduced, and the jerkiness during shifting is minimized, achieving seamless connection in the shifting process.
