Factory fork springs are chosen for an average rider on an average road; few riders are either.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eInner diameter 43.6 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 08437-41\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 4.1 N\/mm\u003c\/li\u003e\n\u003cli\u003eFree length 455 mm\u003c\/li\u003e\n\u003cli\u003eSupplied as a pair\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eProduction is Öhlins' own in Sweden, and the tolerance on the rate is what separates these from a generic replacement. The finish is applied after setting, which means the coating does not affect the rate. Öhlins publishes recommended sag figures for its springs, so the setup has a reference rather than a feel.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eFree length 455 mm, inner diameter 43.6 mm, rate 4.1 N\/mm — those three figures define the part completely.\u003c\/p\u003e\u003ch2\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eSoft rates like this are what off-road and adventure forks need: the wheel has to follow the ground, not deflect off it. A very soft rate uses more of the stroke, which is usually what an off-road chassis wants. Expect more sag and more movement — that is the point, not a fault. A road machine spends most of its life in the first third of the fork's travel — that is the part the rate governs.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eÖhlins offers rates in defined steps so a change can be made in one direction at a time rather than by guesswork. 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? Any workshop with the fork or shock in front of it can answer whether this spring fits — the three figures above are all it needs.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eÖhlins part numbers are stamped on the packaging rather than the spring, so keep the label with the setup notes. Fitting is a fork-oil job: the legs come apart, the springs go in, the oil level is set to specification. Note the original oil level before draining — it is a useful reference even when Öhlins specifies its own.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad 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.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting matters as much as the part.
