Rear spring rate sets ride height, static sag and how much of the damper's stroke is actually usable.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 12 N\/mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003e170 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eFree length 280 mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00281-75\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eThe unit is rebuildable: seals, shims and oil are catalogue items, not a reason to buy a new one. Production has stayed in Sweden since the company was founded in 1976. 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\u003eFree length 280 mm, inner diameter 46 mm, rate 12 N\/mm — those three figures define the part completely.\u003c\/p\u003e\u003ch2\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eThis is the end of the range where small-bump compliance matters more than resistance to diving. The trade is fork dive under braking — noticeable, but rarely the limiting factor on the road. On a machine ridden solo and mostly on the road, softer is often the honest choice. 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\u003eRate and the Linkage\u003c\/h2\u003e\u003cp\u003eÖhlins sells rear springs separately precisely because rider weight varies more than machine weight does. Two riders 20 kg apart on the same motorcycle genuinely need different rates, not different clicks. Progressive springs change rate through the stroke, which suits machines with little travel and a lot of load.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eThis is a service part in the proper sense — it wears, it settles, and replacing it restores what the suspension was designed to do. There is no model list for this size because the spring is a dimensional part: it fits whatever fork it physically fits. 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\u003eThe fork legs come off, the springs are swapped and the oil level is reset — half a day in most workshops. Öhlins states an air gap for this application, and that figure is part of the setting rather than a detail. 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\u003eThis is not a part to rush. Öhlins recommends installation by an authorised service centre, and we are an authorised Öhlins service centre — fitting, servicing and setup all happen here.
