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\u003eInner diameter 57 mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 170 N\/mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 01099-69\u003c\/li\u003e\n\u003cli\u003eFree length 220 mm\u003c\/li\u003e\n\u003cli\u003e87 mm of usable stroke\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eÖhlins publishes recommended sag figures for its springs, so the setup has a reference rather than a feel. Shafts are hardened and surface-treated so the seal has a consistent surface to run against. Two units carrying the same part number behave the same way out of the box, which is the whole point of testing each one.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eFree length 220 mm, inner diameter 57 mm, rate 170 N\/mm — those three figures define the part completely.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eA firm rate keeps the fork high in its stroke under braking, which preserves the geometry when the front is loaded hard. Support under braking improves; small-bump comfort gives a little back. Firm rates also suit machines carrying luggage as a matter of course. 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\u003eWhat the Rear Spring Decides\u003c\/h2\u003e\u003cp\u003eStatic sag at the rear sets the whole chassis attitude — get it wrong and the front geometry goes with it. Öhlins supplies most of its shocks without a spring precisely so the rate can be matched to the rider rather than averaged. Progressive springs change rate through the stroke, which suits machines with little travel and a lot of load.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eIf you are replacing a sagged original, measure its free length first — a tired spring often measures several millimetres short. Where Öhlins lists this size against a particular unit, the listing is a starting point rather than a boundary. 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\u003eInstallation\u003c\/h2\u003e\u003cp\u003eAny suspension workshop can fit these; the fork does not need to leave the bike for long. The job needs no special tools beyond a fork spring compressor and a measuring rod for the oil level. If the fork has not been serviced recently, bushes and seals are worth replacing while it is apart.\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. Any model-specific approval is listed under Applications.\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.
