1. CVT: CVT consist mainly of 2 transmission pulleys and 2 transmission belts. It’s compact, simple design offers seamless shifting between an unlimited amount of varying gear ratios, allowing a smooth rate of acceleration.

2. Crank Shaft: The engine is low speed with high torque and has large diameter bearings for crankshaft connecting rod, increasing the reliability of the bearings.

3. Forced Air-cooled Engine: There are metal fins covering the outside of the cylinders and the heat generated by the engine is released directly into the air when the cooling fan blows air over fins. It has the advantages of simple structure, light weight, wide adaptability to climate change, rapid start up and no need of radiator.

4. High-flow Oil Pump: Reduces the wear of friction pairs and prolongs the engine service life.

5. Lubricating Oil Strainer: Helps removing solid contamination from lubricating oil, largely reducing the wear of friction pairs and prolonging the engine service life.

6. Aluminum Cylinder Head & Body: Improves the heat dissipation capability, cuts the weight and increases the torque of the engine.
