Adding a pillion or luggage changes the load enough that the standard rate stops working.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 60281-38\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 45 N\/mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated black\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eFree length 180 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eProduction is Öhlins' own in Sweden, and the tolerance on the rate is what separates these from a generic replacement. Öhlins winds, heat-sets and then measures every spring individually — the rate on the label is the rate you get. Anodising is hard-coat rather than decorative, which matters on a component exposed to road salt and stone chips.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eFree length 180 mm, inner diameter 46 mm, rate 45 N\/mm — those three figures define the part completely.\u003c\/p\u003e\u003ch2\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eThis is the middle of Öhlins' range — the rate most riders of average weight end up on once sag is set properly. Mid rates suit a solo rider on a road-going machine with occasional spirited use. A mid rate balances support under braking against compliance over the surface, which is why it is the usual starting point. Road surfaces are the hardest test of a spring rate, because the fork has to cope with both a smooth stretch and a broken one.\u003c\/p\u003e\u003ch2\u003eHow a Rear Spring Works\u003c\/h2\u003e\u003cp\u003eÖhlins supplies most of its shocks without a spring precisely so the rate can be matched to the rider rather than averaged. 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\u003eA workshop will pick this spring from its dimensions and the rider's weight, not from a fitment table. Selection is by measurement. If the diameter and free length match your fork, the remaining question is the rate. A spring is one of the few suspension parts that is genuinely interchangeable: same bore, same free length, and it goes in.\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003eNote the original oil level before draining — it is a useful reference even when Öhlins specifies its own. Öhlins part numbers are stamped on the packaging rather than the spring, so keep the label with the setup notes. Check the free length against the old springs before fitting — a sagged original often measures short.\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.
