DescriptionThe whole story▼
Öhlins part number 08790-15 is a pair of fork springs rated at 11.5 N/mm, 260 mm long with a 25.5 mm inner diameter. Spring rate is the single largest variable in how a front end behaves, and it is the one thing no damping adjuster can compensate for.

How Öhlins Makes Them
The unit is rebuildable: seals, shims and oil are catalogue items, not a reason to buy a new one. Öhlins machines its own critical components instead of buying them in, and the tolerances are where the money goes. Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly.
Size and Rate
Free length 260 mm, inner diameter 25.5 mm, rate 11.5 N/mm — those three figures define the part completely.
What This Rate Does
A rate this high is track territory or for a heavy rider: it stops the fork collapsing under sustained heavy braking. This is the stiff end of Öhlins' catalogue, chosen when fork dive rather than grip is the limiting factor. Öhlins offers rates this high only where the application genuinely needs them. Ride quality on the road is decided by rate first and damping second.
Applications
Öhlins offers rates in defined steps so a change can be made in one direction at a time rather than by guesswork. Ask us with the machine and rider weight and we will tell you which rate in this size to take. Öhlins builds springs to dimensions rather than to model lists, so the question is always the same: does the diameter fit, does the length fit, and is the rate right for the rider?
What Fitting Involves
Fork oil should be replaced at the same time — it is already out of the leg. Öhlins part numbers are stamped on the packaging rather than the spring, so keep the label with the setup notes. Oil level is measured from the top of the tube with the fork compressed and the spring removed.
Road Approval
Road approval: not applicable to the spring on its own. Öhlins issues approvals against complete suspension units, not individual springs.
Fitting and Setup Service
Fitting matters as much as the part. We are an authorised Öhlins service centre and carry out installation, servicing and setup ourselves — get in touch and we will arrange it alongside your order.
