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\u003eFree length 45 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 15021-20\u003c\/li\u003e\n\u003cli\u003e15 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eInner diameter 61 mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated black\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 200 N\/mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eEach spring is set before it is measured, so it will not settle and lose rate in service. Öhlins machines its own critical components instead of buying them in, and the tolerances are where the money goes. Production is Öhlins' own in Sweden, and the tolerance on the rate is what separates these from a generic replacement.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eFree length 45 mm, inner diameter 61 mm, rate 200 N\/mm — those three figures define the part completely.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eFirm rates trade some small-bump comfort for support — the right trade on a good surface at speed. A firm rate holds the chassis attitude when the front or rear is loaded hard. Firm rates also suit machines carrying luggage as a matter of course. 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\u003eAdding a pillion or luggage changes the rear load enough that the standard rate stops working properly. A rear spring is the cheapest part of the suspension and the one that decides the most. 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\u003eAny workshop with the fork or shock in front of it can answer whether this spring fits — the three figures above are all it needs. Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units. Rather 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.\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003eAny suspension workshop can fit these; the fork does not need to leave the bike for long. The springs come powder-coated and need no preparation before they go in. Torque the fork caps to the manufacturer's figure; the springs change nothing about the assembly torque.\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\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.
