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\u003e79 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 100 N\/mm\u003c\/li\u003e\n\u003cli\u003eFree length 160 mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eInner diameter 57 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 01091-34\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eMachining, anodising, assembly and testing all happen in the same building rather than across a supply chain. Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly. The unit is rebuildable: seals, shims and oil are catalogue items, not a reason to buy a new one.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eFree length 160 mm, inner diameter 57 mm, rate 100 N\/mm — those three figures define the part completely.\u003c\/p\u003e\u003ch2\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eIf the suspension bottoms out or the geometry collapses under load, this is the direction to go. This end of the range suits heavier riders, two-up use, or a machine ridden hard enough that fork dive becomes the limit. A firm rate holds the chassis attitude when the front or rear is loaded hard. 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. A shock absorber spring carries the whole rear of the machine through a linkage that multiplies its rate several times over — which is why the number on the spring looks so much larger than a fork rate. Öhlins sells rear springs separately precisely because rider weight varies more than machine weight does.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eAsk us with the machine and rider weight and we will tell you which rate in this size to take. If you are replacing a sagged original, measure its free length first — a tired spring often measures several millimetres short. Nothing about the installation changes across a rate range: the mounting, the length and the bore stay the same.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eFitting is a fork-oil job: the legs come apart, the springs go in, the oil level is set to specification. Springs are supplied ready to fit; no cutting, grinding or packing is needed. A spring that is the correct length still needs the preload spacer checked, since installed length is what sets sag.\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\u003eThis is not a part to rush. Öhlins recommends installation by an authorised service centre, and we are an authorised Öhlins service centre — fitting, servicing and setup all happen here.
