The damper can only control the spring it is given; the wrong rate makes every click a compromise.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 05923-09\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003e164 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eInner diameter 70 mm\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 45 N\/mm\u003c\/li\u003e\n\u003cli\u003eFree length 270 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eRates are offered in defined steps, so a change can be made in one direction at a time. Öhlins winds, heat-sets and then measures every spring individually — the rate on the label is the rate you get. Each spring is set before it is measured, so it will not settle and lose rate in service.\u003c\/p\u003e\u003ch2\u003eSize and Rate\u003c\/h2\u003e\u003cp\u003eDimensionally this is a 70 mm × 270 mm spring; within that envelope Öhlins offers a range of rates, and this one is 45 N\/mm.\u003c\/p\u003e\u003ch2\u003eChoosing the Rate\u003c\/h2\u003e\u003cp\u003eIf reaching the sag figure takes almost all of the available preload, the rate is too soft; if sag is reached with none at all, it is too firm. A spring that is too firm keeps the rear high, which quickens the steering but costs rear grip over broken surfaces. Rider weight in full kit, a pillion and luggage all belong in the calculation — the weight of the machine alone does not decide the rate.\u003c\/p\u003e\u003ch2\u003eRate and the Linkage\u003c\/h2\u003e\u003cp\u003eProgressive springs change rate through the stroke, which suits machines with little travel and a lot of load. A spring that has settled in service sits shorter than new, which quietly lowers the rear and slackens the steering. 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\u003eThe safest way to choose is by static sag: set the target figure, and the rate follows from whether you can reach it with preload. Ask us with the machine and rider weight and we will tell you which rate in this size to take. Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eTorque the shock mounting bolts to the manufacturer's figure when the shock goes back in; the new spring changes nothing about those values. Set static sag after fitting; the rate is only right if the sag figure lands where Öhlins specifies. Check the free length against the old spring before fitting — a sagged original often measures short.\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\u003eÖhlins suspension rewards careful fitting. We recommend having the work done by an authorised Öhlins service centre — and we are one ourselves: we fit, service and set up Öhlins components in house. If you would like us to handle the installation, just ask and we will quote it with the order.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 05923-09\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Rate:\u003c\/em\u003e 45 N\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFree Length:\u003c\/em\u003e 270 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 70 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eStroke:\u003c\/em\u003e 164 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eConstruction:\u003c\/em\u003e Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFinish:\u003c\/em\u003e Powder-coated yellow\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53745299882250,"sku":"05923-09","price":116.07,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/RearOhlinsSpring_24981122-4035-41ad-985f-803c778d0070.png?v=1789628447","url":"https:\/\/inter-pace.com\/products\/ohlins-shock-spring-45-n-mm-270-mm-70-mm-05923-09","provider":"Inter-Pace","version":"1.0","type":"link"}
