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 27 N\/mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00180-98\u003c\/li\u003e\n\u003cli\u003ePowder-coated black\u003c\/li\u003e\n\u003cli\u003e107 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eFree length 180 mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eSeals are specified for temperature stability rather than for the lowest unit cost. Two units carrying the same part number behave the same way out of the box, which is the whole point of testing each one. Each spring is set before it is measured, so it will not settle and lose rate in service.\u003c\/p\u003e\u003ch2\u003eSize and Rate\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 180 mm and the inner diameter at 46 mm across this rate range, so moving up or down a rate changes nothing about the installation.\u003c\/p\u003e\u003ch2\u003eChoosing 27 N\/mm\u003c\/h2\u003e\u003cp\u003eA soft rate favours grip and comfort over support: the fork moves early, which keeps the tyre loaded on a poor surface. On a machine ridden solo and mostly on the road, softer is often the honest choice. The trade is fork dive under braking — noticeable, but rarely the limiting factor on the road. 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\u003eRear spring rate sets ride height and static sag, and those two decide the chassis attitude before any damping click matters. The rear spring carries the rider, the pillion and the luggage; the front carries only part of it. Preload adjusts sag within a rate; it does not change the rate, and no amount of it will rescue a spring that is wrong.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eRather 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. Where Öhlins lists this size against a particular unit, the listing is a starting point rather than a boundary. If you are replacing a sagged original, measure its free length first — a tired spring often measures several millimetres short.\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003eÖhlins states an air gap for this application, and that figure is part of the setting rather than a detail. Torque the fork caps to the manufacturer's figure; the springs change nothing about the assembly torque. Fork oil should be replaced at the same time — it is already out of the leg.\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 recommends that its suspension is fitted by an authorised service centre.
