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\u003eFree length 280 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00281-80\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 40 N\/mm\u003c\/li\u003e\n\u003cli\u003e159.4 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 46 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eÖhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted. Anodising is hard-coat rather than decorative, which matters on a component exposed to road salt and stone chips. Öhlins publishes recommended sag figures for its springs, so the setup has a reference rather than a feel.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eFree length 280 mm, inner diameter 46 mm, rate 40 N\/mm — those three figures define the part completely.\u003c\/p\u003e\u003ch2\u003eChoosing 40 N\/mm\u003c\/h2\u003e\u003cp\u003eThis is where most riders of average weight land once static sag has been set to specification. From here it is easy to move one step in either direction once you have ridden it. A mid rate balances support under braking against compliance over the surface, which is why it is the usual starting point. Ride quality on the road is decided by rate first and damping second.\u003c\/p\u003e\u003ch2\u003eRate and the Linkage\u003c\/h2\u003e\u003cp\u003eTwo riders 20 kg apart on the same motorcycle genuinely need different rates, not different clicks. A shock absorber spring carries the whole rear of the machine through a linkage that multiplies its rate several times over — which is why the number on the spring looks so much larger than a fork rate. Because the linkage is progressive on most modern machines, a small change in rate moves the sag more than riders expect.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eAny workshop with the fork or shock in front of it can answer whether this spring fits — the three figures above are all it needs. A workshop will pick this spring from its dimensions and the rider's weight, not from a fitment table. 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\u003eIf the fork has not been serviced recently, bushes and seals are worth replacing while it is apart. Öhlins states the oil and the air-gap for this application — both are part of the setting, not a detail. Once fitted, ride the machine before making damping changes: the new rate alters what the clicks do.\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\u003eFitting matters as much as the part.
