Use oil cooled technology, lighten the heat  capacity, extend of service life for engine.

Can start with any gear,convenience, faster,

flexible.

Lightweight piston, with wear-resistance  surface,thin piston ring,reduce the inertness and  abrasion of piston vertical motion.Improve power  output and increase of servise life for engine.

Use the optimum design of crankshaft, piston,  camshaft, clutch, magneto etc,improve the  engine power.

Lightweight rare earths magneto, permanent  magnetism make longer service life.

Using secondary filtration technology to  reduce the impurity in lubrication to extend  service life,bring easier cleaning.

Clutch driven gear use strengthen alloy material,  cushion gluesheath use special heat-resistance
