Shafts are hardened and surface-treated so the seal has a consistent surface to run against. Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eÖhlins lists this spring for Kawasaki GPZ900R (1999–2000). The rate is chosen for rider weight and riding style, so treat the list as a starting point: a spring of these dimensions fits any fork that takes them.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 440 mm and the inner diameter at 24 mm across this rate range, so moving up or down a rate changes nothing about the installation.\u003c\/p\u003e\u003ch2\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eThis is the middle of Öhlins' range — the rate most riders of average weight end up on once sag is set properly. A mid rate balances support under braking against compliance over the surface, which is why it is the usual starting point. 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 Fitting Involves\u003c\/h2\u003e\u003cp\u003eFork oil should be replaced at the same time — it is already out of the leg. Work on both legs in one session so the fork stays symmetrical. 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: 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\u003eImportant Notes\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eUse the oil and air gap specified in the vehicle manual.\u003c\/li\u003e\u003c\/ul\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 08669-90\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Rate:\u003c\/em\u003e 9.0 N\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFree Length:\u003c\/em\u003e 440 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 24 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePosition:\u003c\/em\u003e Vorne\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eConstruction:\u003c\/em\u003e Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePackaging Unit:\u003c\/em\u003e Pair\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":53644130648330,"sku":"08669-90","price":161.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/ForkSprings-v2_ddab9e2d-383f-4999-b446-3b730a5b626e.png?v=1788852542","url":"https:\/\/inter-pace.com\/products\/ohlins-fork-springs-9-0-n-mm-440-mm-24-mm-08669-90","provider":"Inter-Pace","version":"1.0","type":"link"}
