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 30 mm\u003c\/li\u003e\n\u003cli\u003eFree length 60 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 25059-01\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 15 N\/mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the Rate Holds\u003c\/h2\u003e\u003cp\u003eThe wire is progressively wound where the application calls for it and straight where it does not. Öhlins machines its own critical components instead of buying them in, and the tolerances are where the money goes. Öhlins manufactures in Upplands Väsby, north of Stockholm, and assembles and tests every unit there before it ships.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eThe 30 mm bore and 60 mm length are the two figures that decide whether it physically fits; 15 N\/mm decides whether it suits the rider.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eComfort and grip come from the spring moving early; this is the end of the range where that happens. The trade is fork dive under braking — noticeable, but rarely the limiting factor on the road. Rates in this range suit lighter riders and machines that spend their time on real roads rather than smooth circuits. 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\u003eBecause the linkage is progressive on most modern machines, a small change in rate moves the sag more than riders expect. Rear 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. Adding a pillion or luggage changes the rear load enough that the standard rate stops working properly.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eWhere Öhlins lists this size against a particular unit, the listing is a starting point rather than a boundary. A workshop will pick this spring from its dimensions and the rider's weight, not from a fitment table. Öhlins offers rates in defined steps so a change can be made in one direction at a time rather than by guesswork.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eRate and preload are separate adjustments: get the rate right first, then set sag with preload. Oil level is measured from the top of the tube with the fork compressed and the spring removed. The springs come powder-coated and need no preparation before they go in.\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\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 25059-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Rate:\u003c\/em\u003e 15 N\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFree Length:\u003c\/em\u003e 60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 30 mm\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":53645415186698,"sku":"25059-01","price":118.0,"currency_code":"BAM","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/RearOhlinsSpring_978bc053-cc71-4d4c-9adf-9be8739dc3c6.png?v=1788866902","url":"https:\/\/inter-pace.com\/en-ba\/products\/ohlins-shock-spring-15-n-mm-60-mm-30-mm-25059-01","provider":"Inter-Pace","version":"1.0","type":"link"}
