General description

• High quality workmanship
• A must-have item when adjusting the drive
• Spring designed for Suzuki and Morini engines
• Ensures stable operation even in high temperatures

Note that a hard spring will transmit more torque and a softer spring will have a better effect on performance, but there will be a higher probability of belt slippage. It is necessary to choose between a soft, medium and hard spring, and it should also be remembered that the hardness of the spring affects the engine speed (the harder the spring, the higher the speed).
