Rear spring rate sets ride height, static sag and how much of the damper's stroke is actually usable.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFree length 250 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 60580-08\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 48 N\/mm\u003c\/li\u003e\n\u003cli\u003eInner diameter 57 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eThe 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. The finish is applied after setting, which means the coating does not affect the rate.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eAt 250 mm free length and 57 mm inner diameter, this spring is dimensionally interchangeable with anything of the same size — the rate is what makes it a different part.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eA mid rate balances support under braking against compliance over the surface, which is why it is the usual starting point. This is the middle of Öhlins' range — the rate most riders of average weight end up on once sag is set properly. Mid rates suit a solo rider on a road-going machine with occasional spirited use. 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 sells rear springs separately precisely because rider weight varies more than machine weight does. A spring that has settled in service sits shorter than new, which quietly lowers the bike and steepens the steering. The rear spring carries the rider, the pillion and the luggage; the front carries only part of it.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eThis is a service part in the proper sense — it wears, it settles, and replacing it restores what the suspension was designed to do. Selection is by measurement. If the diameter and free length match your fork, the remaining question is the rate. 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\u003eTorque the fork caps to the manufacturer's figure; the springs change nothing about the assembly torque. Rate and preload are separate adjustments: get the rate right first, then set sag with preload. Any suspension workshop can fit these; the fork does not need to leave the bike for long.\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\u003eÖhlins recommends that its suspension is fitted by an authorised service centre. We are one, and we do the work here: installation, servicing and a proper setup.
