Fork Suspension Springs
Fork Springs
The pair of coil springs in your forks are rated for an "average" weight rider. If you are heavier, lighter, carry a pillion or luggage, ride different terrain or want firmer support you may need a different spring rate than the OEM. See our spring selection article and our FAQ for guidance. We stock multiple spring brands and sizes, with linear (straight) rates and progressive rates. Fork springs are specified by outer diameter (in millimetres) and free length (in millimetres) — use the Fork Spring Search to narrow results.
Match Springs to Rider, Load and Terrain
- Adjust for rider weight, pillion or heavy luggage to reduce front sag
- Choose linear or progressive rates for your riding style
- Balance springs available for air forks to provide correct top-out support
- Preload spacers and washers allow fine tuning without replacing coils
Recommended Pairings
Consider matching springs with our Suspension Tools. See preload parts at coil seats & preload tubes and balance springs at balance springs. For fitting advice read the Teknik Fork Spring Installation Guide and use a Fork Spring Compressor Tool.
