● Adopts single cylinder, four valves, SOHC structure (low air intake resistance, high inflation efficiency, strong power).

● Roller rocker arm, piston eccentric technology (reduce power loss, longer life, strong power).

● Crankshaft and connecting rod adopt bearing shell structure (light weight, low sound, high life and good reliability).

● CFD optimization design of concave top piston (high turbulent kinetic energy, high power and high emission).

● Adopt piston forced back cooling technology (piston heat dissipation fast, heat load low, longer life).

● PVD processing piston ring, cylinder bore with plateau honing cross hatch (more wear-resistant, less oil consumption).

● Starting pressure reducing valve mechanism (easy to start).

● High strength double-sided toothed belt (high transmission efficiency, long service life).

● Gear grinding drive shaft (high efficiency, low noise, long life).

● Using overhead oil and gas separation cycle technology (less exhaust gas emissions, low oil consumption).

● External integral fine filter (convenient maintenance).

● The transmission box adopts maintenance-free breathing valve (beautiful appearance, more environmentally friendly).
