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\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eFree length 270 mm\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 50 N\/mm\u003c\/li\u003e\n\u003cli\u003e145 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eInner diameter 57 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00596-09\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eMachining, anodising, assembly and testing all happen in the same building rather than across a supply chain. Öhlins publishes recommended sag figures for its springs, so the setup has a reference rather than a feel. Öhlins machines its own critical components instead of buying them in, and the tolerances are where the money goes.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 270 mm and the inner diameter at 57 mm across this rate range, so moving up or down a rate changes nothing about the installation.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eMid rates suit a solo rider on a road-going machine with occasional spirited use. This is where most riders of average weight land once static sag has been set to specification. A mid rate balances support under braking against compliance over the surface, which is why it is the usual starting point. 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\u003eRear spring rates run in the tens or hundreds of N\/mm because the spring sits at the short end of that lever, not at the wheel. Öhlins sells rear springs separately precisely because rider weight varies more than machine weight does. Because the linkage is progressive on most modern machines, a small change in rate moves the sag more than riders expect.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eRate is the variable that depends on the rider, not on the machine. Two people on the same bike may well want two different numbers. Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units. If you are replacing a sagged original, measure its free length first — a tired spring often measures several millimetres short.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eÖhlins states an air gap for this application, and that figure is part of the setting rather than a detail. Spring preload spacers may need adjusting to keep the installed length correct. Rate and preload are separate adjustments: get the rate right first, then set sag with preload.\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\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 00596-09\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Rate:\u003c\/em\u003e 50 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 57 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eStroke:\u003c\/em\u003e 145 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":53645325074698,"sku":"00596-09","price":90.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/RearOhlinsSpring_3667bb40-383d-4eff-92b6-8a83c3856a2e.png?v=1788866580","url":"https:\/\/inter-pace.com\/en-ec\/products\/ohlins-shock-spring-50-n-mm-270-mm-57-mm-00596-09","provider":"Inter-Pace","version":"1.0","type":"link"}
