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\u003e43 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 170 N\/mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 60281-13\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eFree length 100 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eSeals are specified for temperature stability rather than for the lowest unit cost. Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted. 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\u003eDimensionally this is a 46 mm × 100 mm spring; within that envelope Öhlins offers a range of rates, and this one is 170 N\/mm.\u003c\/p\u003e\u003ch2\u003eChoosing 170 N\/mm\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. Support under braking improves; small-bump comfort gives a little back. 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\u003eTwo riders 20 kg apart on the same motorcycle genuinely need different rates, not different clicks. Preload adjusts sag within a rate; it does not change the rate, and no amount of it will rescue a spring that is wrong. The damper can only control the spring it is given; the wrong rate makes every setting a compromise.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eThe safest way to choose is by static sag: set the target figure, and the rate follows from whether you can reach it with preload. A spring is one of the few suspension parts that is genuinely interchangeable: same bore, same free length, and it goes in. Nothing about the installation changes across a rate range: the mounting, the length and the bore stay the same.\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. Fitting is a fork-oil job: the legs come apart, the springs go in, the oil level is set to specification. Springs are supplied ready to fit; no cutting, grinding or packing is needed.\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. We are one, and we do the work here: installation, servicing and a proper setup.
