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 160 mm\u003c\/li\u003e\n\u003cli\u003e75 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 105 N\/mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 01091-36\u003c\/li\u003e\n\u003cli\u003eInner diameter 57 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the Rate Holds\u003c\/h2\u003e\u003cp\u003eÖhlins manufactures in Upplands Väsby, north of Stockholm, and assembles and tests every unit there before it ships. The unit is rebuildable: seals, shims and oil are catalogue items, not a reason to buy a new one. Every unit is dyno-tested against the curve held for its part number, not sampled from a batch.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 160 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 105 N\/mm\u003c\/h2\u003e\u003cp\u003eA firm rate holds the chassis attitude when the front or rear is loaded hard. If the suspension bottoms out or the geometry collapses under load, this is the direction to go. 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\u003eOn a linkage-equipped machine the wheel moves several millimetres for every millimetre the damper moves, and the spring rate has to account for that ratio. Adding a pillion or luggage changes the rear load enough that the standard rate stops working properly. 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\u003eThis spring is chosen by its dimensions rather than by motorcycle model: check inner diameter, free length and rate against the fork it is going into. Öhlins lists no fixed model here — the spring is defined by its measurements, and any fork with matching dimensions can take it. Selection is by measurement. If the diameter and free length match your fork, the remaining question is the rate.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eA spring that is the correct length still needs the preload spacer checked, since installed length is what sets sag. Öhlins states an air gap for this application, and that figure is part of the setting rather than a detail. Fitting is a fork-oil job: the legs come apart, the springs go in, the oil level is set to specification.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: not applicable to the spring on its own. Öhlins issues approvals against complete suspension units, not individual springs.\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.
