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\u003e32 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 240 N\/mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 60015-91\u003c\/li\u003e\n\u003cli\u003eInner diameter 57 mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eFree length 85 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the Rate Holds\u003c\/h2\u003e\u003cp\u003eSeals are specified for temperature stability rather than for the lowest unit cost. Machining, anodising, assembly and testing all happen in the same building rather than across a supply chain. The finish is applied after setting, which means the coating does not affect the rate.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eFree length 85 mm, inner diameter 57 mm, rate 240 N\/mm — those three figures define the part completely.\u003c\/p\u003e\u003ch2\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eFirm rates trade some small-bump comfort for support — the right trade on a good surface at speed. A firm rate holds the chassis attitude when the front or rear is loaded hard. This end of the range suits heavier riders, two-up use, or a machine ridden hard enough that fork dive becomes the limit. A road machine spends most of its life in the first third of the fork's travel — that is the part the rate governs.\u003c\/p\u003e\u003ch2\u003eHow a Rear Spring Works\u003c\/h2\u003e\u003cp\u003eStatic sag at the rear sets the whole chassis attitude — get it wrong and the front geometry goes with it. Preload adjusts sag within a rate; it does not change the rate, and no amount of it will rescue a spring that is wrong. On 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.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eÖhlins 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? Öhlins lists no fixed model here — the spring is defined by its measurements, and any fork with matching dimensions can take it. There is no model list for this size because the spring is a dimensional part: it fits whatever fork it physically fits.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eÖhlins states the oil and the air-gap for this application — both are part of the setting, not a detail. Note the original oil level before draining — it is a useful reference even when Öhlins specifies its own. Öhlins part numbers are stamped on the packaging rather than the spring, so keep the label with the setup notes.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: a spring is a like-for-like replacement of a wear part and carries no separate type approval. Where Öhlins states an approval for a particular motorcycle, it is named under Applications.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting matters as much as the part.
