The damper can only control the spring it is given; the wrong rate makes every click a compromise.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e93 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eInner diameter 51 mm\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 100 N\/mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21056-34\u003c\/li\u003e\n\u003cli\u003eFree length 200 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eEvery Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly. Shafts are hardened and surface-treated so the seal has a consistent surface to run against. Two units carrying the same part number behave the same way out of the box, which is the whole point of testing each one.\u003c\/p\u003e\u003ch2\u003eSize and Rate\u003c\/h2\u003e\u003cp\u003eAt 200 mm free length and 51 mm inner diameter, this spring is dimensionally interchangeable with anything of the same size — the rate is what makes it a different part.\u003c\/p\u003e\u003ch2\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eFirm rates trade some small-bump comfort for support — the right trade on a good surface at speed. Heavier riders, two-up use and track days all push the choice towards this end. This end of the range suits heavier riders, two-up use, or a machine ridden hard enough that fork dive becomes the limit. Ride quality on the road is decided by rate first and damping second.\u003c\/p\u003e\u003ch2\u003eWhat the Rear Spring Decides\u003c\/h2\u003e\u003cp\u003eThe damper can only control the spring it is given; the wrong rate makes every setting a compromise. Two riders 20 kg apart on the same motorcycle genuinely need different rates, not different clicks. A spring that has settled in service sits shorter than new, which quietly lowers the bike and steepens the steering.\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. This spring is chosen by its dimensions rather than by motorcycle model: check inner diameter, free length and rate against the fork it is going into. Öhlins offers rates in defined steps so a change can be made in one direction at a time rather than by guesswork.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eThe fork legs come off, the springs are swapped and the oil level is reset — half a day in most workshops. Öhlins part numbers are stamped on the packaging rather than the spring, so keep the label with the setup notes. Torque the fork caps to the manufacturer's figure; the springs change nothing about the assembly torque.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: none is issued for springs as such — they replace an existing component of the same function. Any model-specific approval is listed under Applications.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so the installation does not have to be your problem: we fit and set up Öhlins components in our own workshop.
