Motorcycle Shock Springs
A shock spring is the coil spring fitted to a rear shock absorber. Öhlins notes that a bike sitting unevenly, or a ride height that seems off, may be a sign that the spring or shock is no longer supporting the motorcycle correctly. This page carries shock springs from makers including Öhlins, Progressive Suspension and Hyperpro, listed by bike or by size and rate.
What is on this page
The Öhlins shock springs here are for Harley-Davidson Touring, Softail, Dyna, Sportster and FXR models, and for off-road bikes, including GasGas, Husqvarna and KTM, with some also listed for Honda, Kawasaki and Yamaha. The Progressive Suspension springs are for its 12, 13 and 412 series dual shocks, on Honda, Kawasaki and Suzuki models.
The Hyperpro shock springs here are mostly rear shock spring kits, some of them lowering spring kits that give the drop in millimetres, each titled with the make and, where there is room, the models it is listed for. The MX rear shock springs give their rate in the title. Hyperpro says its shock spring is designed to fit the original shock and replaces the original spring, and lists a rear spring and an installation manual with setup data as the contents of its rear shock spring kit.
Matching a spring
Öhlins titles give the spring's size and its rate, such as 46/220/28 N/mm. Match those figures to your shock's current spring or to the shock maker's specification, and check the bikes named in the title. Several Öhlins springs come in more than one rate for the same shock, such as the 46/220 spring in 26, 28, 32 and 38 N/mm, so you choose the rate rather than the size.
Progressive Suspension makes a shock tool for its own shocks that it says fits many single and twin shocks and takes the hassle out of changing springs; it is on the suspension tools page. Complete shocks are on the shock absorbers page.
Will it fit my bike?
Each spring is titled with the bikes or shocks it is listed for. Check the product page for the exact models and years, and match the size and rate to your shock.
How do I know my spring needs changing?
Öhlins says that if the bike sits unevenly or the ride height seems off, it may be a sign that the spring or shock is no longer supporting the motorcycle correctly. A suspension specialist can confirm it.
