It has compact structure, large horse power and explosive power, especially for tricycle and motorcycle.
 
The semi-open cooling water jacket is adopted, increase the intensity and reduce the deformation of the cylinder. Prolong the service life.
 
The optimized combustion chamber is wedge-shaped structure, which can accelerate the flame transferring speed, knocking is effectively prevented, dynamic performance and economical efficiency are guaranteed. The heat transfer of piston is quick and uniform, raw emissions are reduced.
 
Advanced design of balance system brings less vibration, smooth, comfortable and safe drive.
 
Overhead camshaft, silent chain, needle-bearing rocker arm, valve timing system run stably and has lower noise.
 
Papery oil filter increase the efficiency of lubricating oil cleaning, and ensures the lubricating oil cleanliness of all engine parts. Reduce wear and prolong the service life.
 
With reverse gear inside, transmission smooth and reliable, lower noise and longer service life.
