Factory fork springs are chosen for an average rider on an average road; few riders are either.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFree length 430 mm\u003c\/li\u003e\n\u003cli\u003eSupplied as a pair\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 2.8 N\/mm\u003c\/li\u003e\n\u003cli\u003eInner diameter 31.5 mm\u003c\/li\u003e\n\u003cli\u003e278 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 08794-28\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the Rate Holds\u003c\/h2\u003e\u003cp\u003eÖhlins publishes recommended sag figures for its springs, so the setup has a reference rather than a feel. The finish is applied after setting, which means the coating does not affect the rate. Shafts are hardened and surface-treated so the seal has a consistent surface to run against.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eFree length 430 mm, inner diameter 31.5 mm, rate 2.8 N\/mm — those three figures define the part completely.\u003c\/p\u003e\u003ch2\u003eChoosing 2.8 N\/mm\u003c\/h2\u003e\u003cp\u003eSoft rates like this are what off-road and adventure forks need: the wheel has to follow the ground, not deflect off it. At this rate the fork sits deep in its travel under load, which is exactly what a long-travel chassis is designed around. A very soft rate uses more of the stroke, which is usually what an off-road chassis wants. 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\u003eApplications\u003c\/h2\u003e\u003cp\u003eA workshop will pick this spring from its dimensions and the rider's weight, not from a fitment table. Öhlins offers rates in defined steps so a change can be made in one direction at a time rather than by guesswork. 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.\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003eSpring preload spacers may need adjusting to keep the installed length correct. Öhlins states an air gap for this application, and that figure is part of the setting rather than a detail. The job needs no special tools beyond a fork spring compressor and a measuring rod for the oil level.\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\u003eFitting matters as much as the part.
