A fork that is sprung wrong uses up its travel before the damping has a chance to work.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 13.0 N\/mm\u003c\/li\u003e\n\u003cli\u003eSupplied as a pair\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 08790-13\u003c\/li\u003e\n\u003cli\u003eFree length 260 mm\u003c\/li\u003e\n\u003cli\u003e136 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eInner diameter 25.5 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eThe unit is rebuildable: seals, shims and oil are catalogue items, not a reason to buy a new one. Each spring is set before it is measured, so it will not settle and lose rate in service. Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eFree length 260 mm, inner diameter 25.5 mm, rate 13.0 N\/mm — those three figures define the part completely.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eA rate this high is track territory or for a heavy rider: it stops the fork collapsing under sustained heavy braking. Very firm rates keep the geometry stable but ask the damping to work harder over small inputs. Heavy riders in full kit, or machines carrying substantial load, are the other case. Ride quality on the road is decided by rate first and damping second.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eThe safest way to choose is by static sag: set the target figure, and the rate follows from whether you can reach it with preload. Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units. Rather than a model list, use the measurements: a fork that accepts this diameter and length is a candidate, and the rate follows from rider weight.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eÖhlins part numbers are stamped on the packaging rather than the spring, so keep the label with the setup notes. Work on both legs in one session so the fork stays symmetrical. Both legs are done together, and both take the same rate.\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\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.
