1:Optimized air passage design: brand new air passage design to improve fuel/gas mixing condition,ensuring more complete combustion,which significantly improves fuel consumption and realizes large torque at low speed.

2:Excellent performance:with the same displacement,this engine has better power and torque,and higher adaptability to suit various road conditions.

3:Valve mechanism more rational: A timing valve system with downward camshaft,helical gear transmission and push rod,it is a simple structure with higher transmission stability and reliability.

4:Optimized clutch:multi-disc manual wet clutch is adopted to increase the reserve coefficient and reliability of clutch.

5:Optimized gearshift system: Optimized shift drum contour and stopping plate to make gearshift more flexible.

6:Clutch Mode: Multi-disc manual wet clutch

7:Gearshift Mode:Constant mesh,2-stage transmission,5 gears
