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\u003e110 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 30 N\/mm\u003c\/li\u003e\n\u003cli\u003eFree length 190 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 66419-030\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003ePowder-coated black\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eÖhlins winds, heat-sets and then measures every spring individually — the rate on the label is the rate you get. Shafts are hardened and surface-treated so the seal has a consistent surface to run against. Every unit is dyno-tested against the curve held for its part number, not sampled from a batch.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eThe 46 mm bore and 190 mm length are the two figures that decide whether it physically fits; 30 N\/mm decides whether it suits the rider.\u003c\/p\u003e\u003ch2\u003eChoosing 30 N\/mm\u003c\/h2\u003e\u003cp\u003eThe trade is fork dive under braking — noticeable, but rarely the limiting factor on the road. Rates in this range suit lighter riders and machines that spend their time on real roads rather than smooth circuits. On a machine ridden solo and mostly on the road, softer is often the honest choice. 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\u003eWhat the Rear Spring Decides\u003c\/h2\u003e\u003cp\u003eStatic sag at the rear sets the whole chassis attitude — get it wrong and the front geometry goes with it. On a linkage-equipped machine the wheel moves several millimetres for every millimetre the damper moves, and the spring rate has to account for that ratio. A rear spring is the cheapest part of the suspension and the one that decides the most.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eÖhlins builds springs to dimensions rather than to model lists, so the question is always the same: does the diameter fit, does the length fit, and is the rate right for the rider? Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units. 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\u003eInstallation\u003c\/h2\u003e\u003cp\u003eSet static sag after fitting; the rate is only right if the sag figure lands where Öhlins specifies. Springs are supplied ready to fit; no cutting, grinding or packing is needed. Spring preload spacers may need adjusting to keep the installed length correct.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: springs are not separately type-approved in Germany because they substitute a part that is already homologated with the fork. Model-specific documents, where they exist, are named above.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its suspension is fitted by an authorised service centre. We are one, and we do the work here: installation, servicing and a proper setup.
