For the classification of motorcycles, different countries have different classification methods. International standards (ISO3833-1977) divide motorcycles into two categories according to speed and weight: dual-purpose motorcycles and motorcycles. There are two general classification methods for Chinese motorcycles: one is divided into mopeds and motorcycles according to displacement and maximum design speed. The moped engine has a working volume of no more than 50 ml and a maximum design speed of no more than 50 km. Motorcycle refers to a two- or three-wheeled motorcycle with a working volume of more than 50 ml and a maximum design speed of over 50 km. The other is divided into two categories: two-wheeled vehicles, side tricycles and three-wheeled vehicles according to the number and position of the wheels.
It is customary to categorize by application, structure and engine type and working volume. If you only work in the city, a short-distance travel tool, choose a miniature motorcycle or moped with a compact speed of no more than 50 kilometers. Need to travel frequently between urban and rural areas, can ride two people, should choose an ordinary motorcycle with an engine working volume of 125 ~ 250 ml. If the road conditions are poor, high speed driving or general competition is used, the off-road motorcycle is used.
