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.
