Rear spring rate sets ride height, static sag and how much of the damper's stroke is actually usable.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 90 N\/mm\u003c\/li\u003e\n\u003cli\u003e78 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00281-17\u003c\/li\u003e\n\u003cli\u003eFree length 180 mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eTwo units carrying the same part number behave the same way out of the box, which is the whole point of testing each one. Production is Öhlins' own in Sweden, and the tolerance on the rate is what separates these from a generic replacement. Öhlins machines its own critical components instead of buying them in, and the tolerances are where the money goes.\u003c\/p\u003e\u003ch2\u003eSize and Rate\u003c\/h2\u003e\u003cp\u003eDimensionally this is a 46 mm × 180 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. Support under braking improves; small-bump comfort gives a little back. A firm rate keeps the fork high in its stroke under braking, which preserves the geometry when the front is loaded hard. Ride quality on the road is decided by rate first and damping second.\u003c\/p\u003e\u003ch2\u003eWhat the Rear Spring Decides\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. Preload adjusts sag within a rate; it does not change the rate, and no amount of it will rescue a spring that is wrong. 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.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eSag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units. Any workshop with the fork or shock in front of it can answer whether this spring fits — the three figures above are all it needs. There is no model list for this size because the spring is a dimensional part: it fits whatever fork it physically fits.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eIf the fork has not been serviced recently, bushes and seals are worth replacing while it is apart. Torque the fork caps to the manufacturer's figure; the springs change nothing about the assembly torque. 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 recommends that its suspension is fitted by an authorised service centre.
