Adding a pillion or luggage changes the load enough that the standard rate stops working.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eFree length 285 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00281-45\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 20 N\/mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003e168 mm of usable stroke\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eMachining, anodising, assembly and testing all happen in the same building rather than across a supply chain. Production has stayed in Sweden since the company was founded in 1976. Anodising is hard-coat rather than decorative, which matters on a component exposed to road salt and stone chips.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eThe 46 mm bore and 285 mm length are the two figures that decide whether it physically fits; 20 N\/mm decides whether it suits the rider.\u003c\/p\u003e\u003ch2\u003eChoosing 20 N\/mm\u003c\/h2\u003e\u003cp\u003eA soft rate favours grip and comfort over support: the fork moves early, which keeps the tyre loaded on a poor surface. The trade is fork dive under braking — noticeable, but rarely the limiting factor on the road. Comfort and grip come from the spring moving early; this is the end of the range where that happens. Road surfaces are the hardest test of a spring rate, because the fork has to cope with both a smooth stretch and a broken one.\u003c\/p\u003e\u003ch2\u003eRate and the Linkage\u003c\/h2\u003e\u003cp\u003eBecause the linkage is progressive on most modern machines, a small change in rate moves the sag more than riders expect. The damper can only control the spring it is given; the wrong rate makes every setting a compromise. A rear spring is the cheapest part of the suspension and the one that decides the most.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eIf you are replacing a sagged original, measure its free length first — a tired spring often measures several millimetres short. 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? A spring is one of the few suspension parts that is genuinely interchangeable: same bore, same free length, and it goes in.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eCheck the free length against the old springs before fitting — a sagged original often measures short. Torque the fork caps to the manufacturer's figure; the springs change nothing about the assembly torque. Öhlins states the oil and the air-gap for this application — both are part of the setting, not a detail.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: springs are not separately type-approved in Germany because they substitute a part that is already homologated with the fork. Model-specific documents, where they exist, are named above.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting matters as much as the part.
