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\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eFree length 200 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00180-55\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 90 N\/mm\u003c\/li\u003e\n\u003cli\u003e90 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eEvery unit is dyno-tested against the curve held for its part number, not sampled from a batch. Anodising is hard-coat rather than decorative, which matters on a component exposed to road salt and stone chips. Materials read unremarkably on paper — aluminium, steel, nitrogen — and the difference lies in how precisely they are made.\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\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eIf the suspension bottoms out or the geometry collapses under load, this is the direction to go. Support under braking improves; small-bump comfort gives a little back. A firm rate holds the chassis attitude when the front or rear is loaded hard. 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\u003eWhat the Rear Spring Decides\u003c\/h2\u003e\u003cp\u003eÖhlins sells rear springs separately precisely because rider weight varies more than machine weight does. The rear spring carries the rider, the pillion and the luggage; the front carries only part of it. Progressive springs change rate through the stroke, which suits machines with little travel and a lot of load.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eSelection is by measurement. If the diameter and free length match your fork, the remaining question is the rate. Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units. Ask us with the machine and rider weight and we will tell you which rate in this size to take.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eBoth legs are done together, and both take the same rate. Check the free length against the old springs before fitting — a sagged original often measures short. Preload spacers usually need shortening or lengthening so the installed length stays correct.\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\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins components deliver what they promise once they are fitted and set up properly. As an authorised Öhlins service centre we do exactly that in house — installation, service and setup.
