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\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00180-34\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 40 N\/mm\u003c\/li\u003e\n\u003cli\u003e107 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eFree length 220 mm\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the Rate Holds\u003c\/h2\u003e\u003cp\u003eShafts are hardened and surface-treated so the seal has a consistent surface to run against. Öhlins winds, heat-sets and then measures every spring individually — the rate on the label is the rate you get. Service parts stay available for years after a part number leaves the current price list.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eThe 46 mm bore and 220 mm length are the two figures that decide whether it physically fits; 40 N\/mm decides whether it suits the rider.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eFrom here it is easy to move one step in either direction once you have ridden it. This is where most riders of average weight land once static sag has been set to specification. Mid rates suit a solo rider on a road-going machine with occasional spirited use. Ride quality on the road is decided by rate first and damping second.\u003c\/p\u003e\u003ch2\u003eWhat the Rear Spring Decides\u003c\/h2\u003e\u003cp\u003eAdding a pillion or luggage changes the rear load enough that the standard rate stops working properly. Progressive springs change rate through the stroke, which suits machines with little travel and a lot of load. Two riders 20 kg apart on the same motorcycle genuinely need different rates, not different clicks.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eRather than a model list, use the measurements: a fork that accepts this diameter and length is a candidate, and the rate follows from rider weight. If you are replacing a sagged original, measure its free length first — a tired spring often measures several millimetres short. Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eFork oil should be replaced at the same time — it is already out of the leg. Preload spacers usually need shortening or lengthening so the installed length stays correct. The fork legs come off, the springs are swapped and the oil level is reset — half a day in most workshops.\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.
