Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted. The finish is applied after setting, which means the coating does not affect the rate.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 270 mm and the inner diameter at 23.5 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\u003eFrom here it is easy to move one step in either direction once you have ridden it. This is where most riders of average weight land once static sag has been set to specification. Mid rates suit a solo rider on a road-going machine with occasional spirited use. Ride quality on the road is decided by rate first and damping second.\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. 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. Rather than a model list, use the measurements: a fork that accepts this diameter and length is a candidate, and the rate follows from rider weight.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eOnce fitted, ride the machine before making damping changes: the new rate alters what the clicks do. If the fork has not been serviced recently, bushes and seals are worth replacing while it is apart. 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: no separate certificate. The spring changes the rate, not the construction of the fork, and is treated as a service part.\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 08429-85\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Rate:\u003c\/em\u003e 8.5 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 23.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eStroke:\u003c\/em\u003e 148 mm\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":53645378355466,"sku":"08429-85","price":161.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/ForkSprings-v2_df463bd5-3af5-43e1-85db-5adc918e7f5b.png?v=1788864059","url":"https:\/\/inter-pace.com\/products\/ohlins-fork-springs-8-5-n-mm-270-mm-23-5-mm-08429-85","provider":"Inter-Pace","version":"1.0","type":"link"}
