Spring rate guide

The spring rate determines the shock’s stiffness and will depend on your weight, personal preference and type of riding. For smooth and mellow enduro, you can opt for a lighter sping whereas agressive riders and MX riders might want to go one level higher.

In addition, we recommend going one level above the normal rate if you have the MTO Racing Swingarm or another aftermarket swingarm that is longer than the stock. I (Quentin) personally like good support so I went with the 450 lbs spring as I weight 50kg.
