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\u003e75 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 01093-29\u003c\/li\u003e\n\u003cli\u003eInner diameter 57 mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eFree length 150 mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 90 N\/mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the Rate Holds\u003c\/h2\u003e\u003cp\u003eÖhlins manufactures in Upplands Väsby, north of Stockholm, and assembles and tests every unit there before it ships. Production is Öhlins' own in Sweden, and the tolerance on the rate is what separates these from a generic replacement. Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly.\u003c\/p\u003e\u003ch2\u003eSize and Rate\u003c\/h2\u003e\u003cp\u003eDimensionally this is a 57 mm × 150 mm spring; within that envelope Öhlins offers a range of rates, and this one is 90 N\/mm.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eFirm rates also suit machines carrying luggage as a matter of course. Heavier riders, two-up use and track days all push the choice towards this end. Support under braking improves; small-bump comfort gives a little back. 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 the Rear Spring Decides\u003c\/h2\u003e\u003cp\u003eProgressive springs change rate through the stroke, which suits machines with little travel and a lot of load. Rear spring rates run in the tens or hundreds of N\/mm because the spring sits at the short end of that lever, not at the wheel. The damper can only control the spring it is given; the wrong rate makes every setting a compromise.\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. Ask us with the machine and rider weight and we will tell you which rate in this size to take. Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units.\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003ePreload spacers usually need shortening or lengthening so the installed length stays correct. Work on both legs in one session so the fork stays symmetrical. Öhlins states the oil and the air-gap for this application — both are part of the setting, not a detail.\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\u003eWe are an authorised Öhlins service centre, so the installation does not have to be your problem: we fit and set up Öhlins components in our own workshop.
