use micro-arc oxidation treatment for piston

head, extend piston uselife.

Wider friction plate and spring shock  absorber, increases the friction distance,  increase reliability.

Crankcase use the shock absorption  sleeve design hanging hole, reduce engine  vibration, improve the ride comfort.

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

Wider crankshaft needle, enhance needle  wear resistance and the reliability.

Special alloy cast iron cylinder liner for  water cooled, higher durable, the cylinder  body use platform netted technology, so  that the formation of oil film is more easilerImproved lubrication for cylinder, piston and  piston ring, improved parts reliability.

Special oil pump for powder metallurgy gear,  improves oil pump gear high temperature  resistance and oil resistance, engine  lubrication more stable.

More thicker main and counter shaft gears,  engine bearing performance more stronger.  More thicker electric starting gears,  improved the strength of gear, specifical  design of water-cool.
