DescriptionThe whole story▼
Öhlins part number 08436-55 is a pair of fork springs rated at 5.5 N/mm, 452 mm long with a 43 mm inner diameter. A fork that is sprung wrong uses up its travel before the damping has a chance to work.

Manufacture and Tolerance
Service parts stay available for years after a part number leaves the current price list. Öhlins machines its own critical components instead of buying them in, and the tolerances are where the money goes. Anodising is hard-coat rather than decorative, which matters on a component exposed to road salt and stone chips.
Size and Rate
At 452 mm free length and 43 mm inner diameter, this spring is dimensionally interchangeable with anything of the same size — the rate is what makes it a different part.
Choosing 5.5 N/mm
This is the end of the range where small-bump compliance matters more than resistance to diving. Rates in this range suit lighter riders and machines that spend their time on real roads rather than smooth circuits. Lighter riders usually end up a step or two below the factory rate once sag is measured properly. Ride quality on the road is decided by rate first and damping second.
Applications
Selection is by measurement. If the diameter and free length match your fork, the remaining question is the rate. A workshop will pick this spring from its dimensions and the rider's weight, not from a fitment table. 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?
Installation
Oil level is measured from the top of the tube with the fork compressed and the spring removed. Preload spacers usually need shortening or lengthening so the installed length stays correct. Fork oil should be replaced at the same time — it is already out of the leg.
Road Approval
Road approval: a spring is a like-for-like replacement of a wear part and carries no separate type approval. Where Öhlins states an approval for a particular motorcycle, it is named under Applications.
Fitting and Setup Service
Öhlins components deliver what they promise once they are fitted and set up properly. As an authorised Öhlins service centre we do exactly that in house — installation, service and setup. Simply ask if you would like us to take care of it.
