Product Description

 

   The commonly used steel types for motorcycle frames include chromium molybdenum steel and ordinary carbon steel.
   Chromium molybdenum steel: This type of steel has high strength and toughness, and is commonly used to manufacture high-strength motorcycle frames.
   Chromium molybdenum steel has good wear resistance and toughness, making it suitable for use in complex road conditions
   Carbon steel: carbon steel has a lower cost and is suitable for mid to low end motorcycles. It has good strength and plasticity, but is relatively heavy.
   The selection of these steel grades mainly depends on the positioning, cost considerations, and performance requirements of the motorcycle.

    Car roll cage is usually made of cold drawn precision seamless steel pipes. This material is formed through a bending process, and during installation, steel pipes are connected or welded together one by one according to the contour of the interior of the carriage, ensuring the robustness and stability of the roll cage. In addition, the roll cage can also be made of high-strength steel, which has the characteristics of high strength and lightweight, and can provide better protection effect.
