The sports racing motorcycle is mainly composed of three parts: the cylinder head, the cylinder block and the crankcase. The cylinder head is made of aluminum alloy and has a heat sink. The new four-stroke motorcycle engine adopts overhead valve and chain transmission. , overhead camshaft structure.
The cylinder block material of the sports racing motorcycle is made of bimetal (abrasion-resistant cast iron cylinder liner cast aluminum heat sink) for better heat dissipation. Some motorcycles use wear-resistant cast iron cylinders, and the crankcase is made of aluminum alloy die-casting. Some motorcycles have a buffer block between the heat dissipation signs to suppress the noise emitted by the heat sink vibration.
Sports racing motorcycle use features
1. The engine of a sports racing motorcycle is a two-stroke or four-stroke gasoline engine.
2. Sports racing motorcycles are mainly air-cooled and cooled. They are naturally air-cooled and forced air-cooled. The general models are mainly driven by the air blown through the cylinder head and the heat sink on the cylinder liner. The natural air cooling method of heat. In order to ensure low speed and cooling of the engine before starting, the high-power motorcycle engine uses a forced air-cooling method that uses a fan and an air hood to blow the cooling fins with forced air.
