These motorcycle suspension spring tables are here to simplify the spring selection process. Be sure to read the instructions below to ensure you get the best fit.

The Springs Function:
The spring is used to support the weight of the rider and bike, while damping determines how the suspension responds to a given obstacle. Spring rate is relatively constant, regardless of conditions or riding ability. There are special scenarios where more or less preload is desired to promote better handling characteristics for a given terrain. Too firm of a spring will over-support and resist compressing when demanded. Too soft a spring will ride further into the stroke where the damping and resistance ramp up much too quickly. Having a spring just right for you is crucial to proper suspension characteristics.

Springs are not a substitute for poor valving. Valving and springs go hand in hand to provide traction, comfort, and control. If you are unhappy with your suspensions performance after installing proper springs, this is a sure sign your valving, preload, or setup is incorrect.

Be sure to take careful note of spring preload when installing. Too much preload is a common issue for pushing in corners, deflection, and initial harshness. Many bikes (Ex. Beta) come from the factory with excessive fork preload, which results in the issues stated.

Riders that sit frequently will tend to place less weight on the front of the bike. This usually translates into better handling with a rate softer fork spring.

 

Taller riders tend to place more weight bias over the rear of the bike. This usually requires more support from the shock spring. If over 6’2” we recommend opting for the next firmer rate.

In most cases we recommend rounding up if in between rates. A firmer spring with less preload and softer valving will generally have a better feel.

Feel free to make your own corrections as you see fit. If you are still unsure or are looking for guidance, please contact us! We always appreciate feedback from our fellow friends and riders.

Thanks.
