KOSO Torque Spring 1000RPM, White for GY6 125 / GY6 150 - FH206103

These high quality compression springs are coated with a unique, high-efficiency heat-resistant coating that sustains perfect spring tension and deters heat build-up. Standard compression springs will heat up changing the tension of the spring resulting in erratic shift patterns. Different spring tensions can be selected for different types of riding. 

D4.0X57.5X150L

It is a common rule that the stronger the compression spring, the higher the engine will rev before launching off the starting line. 

• High-efficiency coating to resist heat build-build up 
• High-efficiency coating keeps springs tension consistent at all times 
• All springs are marked for designated rpm performance
