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\u003eMeasured spring rate 30 N\/mm\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eFree length 200 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 66420-030\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eThe wire is progressively wound where the application calls for it and straight where it does not. Machining, anodising, assembly and testing all happen in the same building rather than across a supply chain. Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eAt 200 mm free length and 46 mm inner diameter, this spring is dimensionally interchangeable with anything of the same size — the rate is what makes it a different part.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eRates in this range suit lighter riders and machines that spend their time on real roads rather than smooth circuits. Lighter riders usually end up a step or two below the factory rate once sag is measured properly. A soft rate favours grip and comfort over support: the fork moves early, which keeps the tyre loaded on a poor surface. 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\u003eHow a Rear Spring Works\u003c\/h2\u003e\u003cp\u003eAdding a pillion or luggage changes the rear load enough that the standard rate stops working properly. The rear spring carries the rider, the pillion and the luggage; the front carries only part of it. The damper can only control the spring it is given; the wrong rate makes every setting a compromise.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eÖhlins offers rates in defined steps so a change can be made in one direction at a time rather than by guesswork. If you are replacing a sagged original, measure its free length first — a tired spring often measures several millimetres short. This spring is chosen by its dimensions rather than by motorcycle model: check inner diameter, free length and rate against the fork it is going into.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eSpring preload spacers may need adjusting to keep the installed length correct. Fork oil should be replaced at the same time — it is already out of the leg. Öhlins part numbers are stamped on the packaging rather than the spring, so keep the label with the setup notes.\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\u003eFitting matters as much as the part. We are an authorised Öhlins service centre and carry out installation, servicing and setup ourselves — get in touch and we will arrange it alongside your 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 66420-030\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Rate:\u003c\/em\u003e 30 N\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFree Length:\u003c\/em\u003e 200 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 46 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":53645457752330,"sku":"66420-030","price":75.33,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/RearOhlinsSpring_8ee30082-7ab0-4699-9a91-56d0380d168d.png?v=1788867023","url":"https:\/\/inter-pace.com\/products\/ohlins-shock-spring-30-n-mm-200-mm-46-mm-66420-030","provider":"Inter-Pace","version":"1.0","type":"link"}
