◆ The integral cylinder head can ensure the assembly accuracy of camshaft bearing, eliminating the camshaft bearing failure which often occurs on the split cylinder head.
◆ Increasing the intake valve diameter, cross-sectional area of the intake passage accordingly and valve lift accordingly, which can effectively improve the gas circulation and improve power.
◆ The design of special - shaped top piston can help the gas to tumble in cylinder, and promote oil and gas fully mixed, improve combustion efficiency, reduce fuel consumption and reduce emissions level.
◆ Design the piston back cooling, reducing the temperature of the top of the piston, reducing the piston thermal deformation, improving reliability to cylinder, piston and piston ring.
◆ Crankcase volume increased 15-20% and oil increases 150ml accordingly, which significantly increase the oil cooling and heat dissipation effect. The oil temperature can keep below 115°C.
◆ Deigned two lifting lugs for the rear shock absorb on crankcase, so this engine is suitable to many kinds of scooter frame.
◆ Split design is made between gear box cover and left crankcase, which allows the engine match drum brake or disc brakes to the rear wheels.
