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 66514-140\u003c\/li\u003e\n\u003cli\u003eFree length 140 mm\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 140 N\/mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eProduction has stayed in Sweden since the company was founded in 1976. 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\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 140 mm and the inner diameter at 46 mm across this rate range, so moving up or down a rate changes nothing about the installation.\u003c\/p\u003e\u003ch2\u003eChoosing 140 N\/mm\u003c\/h2\u003e\u003cp\u003eA firm rate keeps the fork high in its stroke under braking, which preserves the geometry when the front is loaded hard. If the suspension bottoms out or the geometry collapses under load, this is the direction to go. Firm rates trade some small-bump comfort for support — the right trade on a good surface at speed. 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. Adding a pillion or luggage changes the rear load enough that the standard rate stops working properly. 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\u003eSelection is by measurement. If the diameter and free length match your fork, the remaining question is the rate. The safest way to choose is by static sag: set the target figure, and the rate follows from whether you can reach it with preload. Ask us with the machine and rider weight and we will tell you which rate in this size to take.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eOnce fitted, ride the machine before making damping changes: the new rate alters what the clicks do. If the fork has not been serviced recently, bushes and seals are worth replacing while it is apart. Preload spacers usually need shortening or lengthening so the installed length stays correct.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: not applicable to the spring on its own. Öhlins issues approvals against complete suspension units, not individual springs.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting matters as much as the part.
