The wire is progressively wound where the application calls for it and straight where it does not. Every unit is dyno-tested against the curve held for its part number, not sampled from a batch.\u003c\/p\u003e\u003ch2\u003eSize and Rate\u003c\/h2\u003e\u003cp\u003eThe 61 mm bore and 240 mm length are the two figures that decide whether it physically fits; 90 N\/mm decides whether it suits the rider.\u003c\/p\u003e\u003ch2\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eHeavier 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. Firm rates trade some small-bump comfort for support — the right trade on a good surface at speed. 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 shock absorber spring carries the whole rear of the machine through a linkage that multiplies its rate several times over — which is why the number on the spring looks so much larger than a fork rate. Öhlins sells rear springs separately precisely because rider weight varies more than machine weight does.\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. Öhlins lists no fixed model here — the spring is defined by its measurements, and any fork with matching dimensions can take it. 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\u003eThe job needs no special tools beyond a fork spring compressor and a measuring rod for the oil level. Öhlins states the oil and the air-gap for this application — both are part of the setting, not a detail. The fork legs come off, the springs are swapped and the oil level is reset — half a day in most workshops.\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\u003eThis is not a part to rush. Öhlins recommends installation by an authorised service centre, and we are an authorised Öhlins service centre — fitting, servicing and setup all happen here.
