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\u003eÖhlins part number 00580-24\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 80 N\/mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eInner diameter 57 mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003e122 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eFree length 250 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eAnodising is hard-coat rather than decorative, which matters on a component exposed to road salt and stone chips. Öhlins publishes recommended sag figures for its springs, so the setup has a reference rather than a feel. Materials read unremarkably on paper — aluminium, steel, nitrogen — and the difference lies in how precisely they are made.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 250 mm and the inner diameter at 57 mm across this rate range, so moving up or down a rate changes nothing about the installation.\u003c\/p\u003e\u003ch2\u003eChoosing 80 N\/mm\u003c\/h2\u003e\u003cp\u003eA firm rate holds the chassis attitude when the front or rear is loaded hard. Heavier riders, two-up use and track days all push the choice towards this end. Firm rates trade some small-bump comfort for support — the right trade on a good surface at speed. 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\u003eHow a Rear Spring Works\u003c\/h2\u003e\u003cp\u003eTwo riders 20 kg apart on the same motorcycle genuinely need different rates, not different clicks. Progressive springs change rate through the stroke, which suits machines with little travel and a lot of load. 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 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?\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003eThe springs come powder-coated and need no preparation before they go in. Torque the fork caps to the manufacturer's figure; the springs change nothing about the assembly torque. Once fitted, ride the machine before making damping changes: the new rate alters what the clicks do.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: none is issued for springs as such — they replace an existing component of the same function.
