Water-cooled engine is the mainstream engine at present, with high cooling efficiency and reliable operation. The technology of domestic water-cooled motorcycles is basically imported from Honda or Yamaha, which is widely used in scooters. At present, the domestic water-cooled motorcycles with better quality are Feng Chun in Zhejiang (Honda Technology) and Linhai in Jiangsu (Yamaha Technology), both of which are used on large scooters.
The disadvantage is that maintenance is more troublesome. After two years of operation, be sure to add antifreeze, preferably replacement. Of course, you need to pay attention to check whether the scale is too thick. Regular cleaning is also necessary, otherwise the cooling effect is not ideal and the cylinder is pulled.
