◆ Performance is more excellent than other domestic 250 cc engine.
◆ Optimizing the design of crank connecting rod mechanism and adding the balance shaft structure, which greatly reduces the vibration of the vehicle.
◆ Optimizing the design of air passage according to the principle of aerodynamics, which reduce the air intake resistance and make air intake more smoothly.
◆ Lightweight design is with the short piston skirt and ultra-thin piston ring, which effectively reduce the power loss.
◆ The oil cooling technology can reduce the working heat load of the engine and improve the working life of the engine.
◆ Bigger cylinder, longer cylinder head fin, and ensuring that upper cross section area of the cooling passage of combustion chamber and air pass no barrier at the same time, which can ensure the sufficient heat dissipation ability and avoid engine power drop caused by high temperature.
