Special piston for water cool engine, bigger work  space and engine compression ratio, raised engine  power output. use micro-arc oxidation treatment for  piston head, extend piston uselife.

Imported FCC friction plates, make it more wear-  resisting, extend clutch uselife.

Right crank use unique disc-and-wiper design,  effective deposition of impurities, cleaner oil which  will into the crankshaft needle and piston, to make  crankshaft and piston moredurable.

Special right cover for water cool, use special cleaning  repeated used fine filter design, steel mesh, more  convenient for cleaning, oil more cleaner.

Crankshaft roller using imported materials, enhanced  the needle strength. extend parts uselife.

Special alloy cast iron cylinder liner for water cooled,
