Product Parameters

 

 

The materials of motorcycle pillars mainly include carbon steel and alloy steel,.
    1.Carbon steel: Carbon steel is a type of steel containing carbon elements, which has good strength and plasticity, relatively low cost, and is currently one of the most widely used materials for motorcycle pillars
    2.Alloy steel: In addition to carbon, alloy steel also contains other alloying elements, which have high strength and hardness. It is suitable for use in high load, high-strength motorcycles, but the cost is relatively high
