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\u003eÖhlins part number 06420-16\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 64 N\/mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003e120 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eInner diameter 63 mm\u003c\/li\u003e\n\u003cli\u003eFree length 250 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\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 sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 250 mm and the inner diameter at 63 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\u003eFirm rates also suit machines carrying luggage as a matter of course. Firm rates trade some small-bump comfort for support — the right trade on a good surface at speed. If the suspension bottoms out or the geometry collapses under load, this is the direction to go. Ride quality on the road is decided by rate first and damping second.\u003c\/p\u003e\u003ch2\u003eRate and the Linkage\u003c\/h2\u003e\u003cp\u003eOn a linkage-equipped machine the wheel moves several millimetres for every millimetre the damper moves, and the spring rate has to account for that ratio. Progressive springs change rate through the stroke, which suits machines with little travel and a lot of load. 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\u003eIf you are replacing a sagged original, measure its free length first — a tired spring often measures several millimetres short. Öhlins lists no fixed model here — the spring is defined by its measurements, and any fork with matching dimensions can take it. 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\u003eFork oil should be replaced at the same time — it is already out of the leg. If the fork has not been serviced recently, bushes and seals are worth replacing while it is apart. Öhlins states an air gap for this application, and that figure is part of the setting rather than a detail.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: not applicable to the spring on its own. Öhlins issues approvals against complete suspension units, not individual springs.\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 06420-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Rate:\u003c\/em\u003e 64 N\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFree Length:\u003c\/em\u003e 250 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 63 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eStroke:\u003c\/em\u003e 120 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":53645364691210,"sku":"06420-16","price":239000.0,"currency_code":"CDF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/RearOhlinsSpring_7ec8e467-5d04-431a-b363-257939c4c379.png?v=1788866788","url":"https:\/\/inter-pace.com\/en-cd\/products\/ohlins-shock-spring-64-n-mm-250-mm-63-mm-06420-16","provider":"Inter-Pace","version":"1.0","type":"link"}
