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\u003eÖhlins part number 00281-79\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 35 N\/mm\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eFree length 290 mm\u003c\/li\u003e\n\u003cli\u003e172.1 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eThe finish is applied after setting, which means the coating does not affect the rate. Machining, anodising, assembly and testing all happen in the same building rather than across a supply chain. Shafts are hardened and surface-treated so the seal has a consistent surface to run against.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eDimensionally this is a 46 mm × 290 mm spring; within that envelope Öhlins offers a range of rates, and this one is 35 N\/mm.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eA softer rate keeps the tyre loaded on a poor surface, which is worth more than outright support on most roads. Comfort and grip come from the spring moving early; this is the end of the range where that happens. This is the end of the range where small-bump compliance matters more than resistance to diving. 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\u003eRear spring rates run in the tens or hundreds of N\/mm because the spring sits at the short end of that lever, not at the wheel. Progressive springs change rate through the stroke, which suits machines with little travel and a lot of load. A rear spring is the cheapest part of the suspension and the one that decides the most.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eIf you are replacing a sagged original, measure its free length first — a tired spring often measures several millimetres short. Selection is by measurement. If the diameter and free length match your fork, the remaining question is the rate. A spring is one of the few suspension parts that is genuinely interchangeable: same bore, same free length, and it goes in.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eÖhlins supplies a setting sheet with the springs; the numbers on it assume the specified oil. Fitting is a fork-oil job: the legs come apart, the springs go in, the oil level is set to specification. 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: a spring is a like-for-like replacement of a wear part and carries no separate type approval. Where Öhlins states an approval for a particular motorcycle, it is named under Applications.\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.
