Motorcycle Fork Suspension Springs

Fork Springs - Linear

Fork Springs - Progressive

Balance Springs PSF

Fork Spring Hardware

The pair of coil springs in your forks are rated for an "average" weight rider. But are you average? Are you bigger or smaller than your bike's factory test rider? Do you ride very different terrain? Do you carry a pillion passenger? Or lots of motorcycling gear? You may need a different rate spring than what your OEM manufacturer was expecting - see our spring selection article for more info.

We offer multiple spring brands in many sizes and in many spring rates - including linear (straight) rates as well as progressive rates which start softer and get firmer during the suspension travel. Fork springs are measured using their outer diameter (in millimetres), as they need to be small enough to fit inside the damper tubes, and their total height with no pre-load applied (also in millimetres). If you know what size you want, you can quickly narrow down our whole list using our Fork Spring Search tool!
