A rear spring matched to rider and load keeps the chassis attitude where the factory intended it.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00280-18\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003e128 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eFree length 200 mm\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 18 N\/mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eEvery unit is dyno-tested against the curve held for its part number, not sampled from a batch. The wire is progressively wound where the application calls for it and straight where it does not. Materials read unremarkably on paper — aluminium, steel, nitrogen — and the difference lies in how precisely they are made.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 200 mm and the inner diameter at 46 mm across this rate range, so moving up or down a rate changes nothing about the installation.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eRates in this range suit lighter riders and machines that spend their time on real roads rather than smooth circuits. A soft rate favours grip and comfort over support: the fork moves early, which keeps the tyre loaded on a poor surface. This is the end of the range where small-bump compliance matters more than resistance to diving. 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\u003eWhat the Rear Spring Decides\u003c\/h2\u003e\u003cp\u003eÖhlins supplies most of its shocks without a spring precisely so the rate can be matched to the rider rather than averaged. A spring that has settled in service sits shorter than new, which quietly lowers the bike and steepens the steering. Rear spring rate sets ride height and static sag, and those two decide the chassis attitude before any damping click matters.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eRate is the variable that depends on the rider, not on the machine. Two people on the same bike may well want two different numbers. 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. Öhlins lists no fixed model here — the spring is defined by its measurements, and any fork with matching dimensions can take it.\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003eÖhlins states the oil and the air-gap for this application — both are part of the setting, not a detail. Öhlins states an air gap for this application, and that figure is part of the setting rather than a detail. Check the free length against the old springs before fitting — a sagged original often measures short.\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.
