Typically, motorbike shock springs are made from the following types of elastic material:

1. High-quality spring steel: spring steel has a high carbon content, good hardness, toughness and fatigue resistance, making it suitable for making shock springs and a relatively common material.2. Alloy steel: Alloy steel is more resistant to wear and tear than normal carbon steel and has better strength and toughness. Alloy steel is also used in some high-speed sports motorbikes.3. Titanium: Titanium is a lightweight, high-strength material that is more suitable for springs in the shock absorbing systems of high-performance, high-speed sport bikes.In general, the choice of material for motorbike shock springs depends on a number of factors such as the environment in which they are used, the needs of the application, and the economic cost.
