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\u003e66 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eFree length 150 mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 01093-89\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 210 N\/mm\u003c\/li\u003e\n\u003cli\u003eInner diameter 57 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the Rate Holds\u003c\/h2\u003e\u003cp\u003eMachining, anodising, assembly and testing all happen in the same building rather than across a supply chain. Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted. The finish is applied after setting, which means the coating does not affect the rate.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eDimensionally this is a 57 mm × 150 mm spring; within that envelope Öhlins offers a range of rates, and this one is 210 N\/mm.\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. A road machine spends most of its life in the first third of the fork's travel — that is the part the rate governs.\u003c\/p\u003e\u003ch2\u003eRate and the Linkage\u003c\/h2\u003e\u003cp\u003eRear spring rate sets ride height and static sag, and those two decide the chassis attitude before any damping click matters. On a linkage-equipped machine the wheel moves several millimetres for every millimetre the damper moves, and the spring rate has to account for that ratio. 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\u003eNothing about the installation changes across a rate range: the mounting, the length and the bore stay the same. Selection is by measurement. If the diameter and free length match your fork, the remaining question is the rate. There is no model list for this size because the spring is a dimensional part: it fits whatever fork it physically fits.\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003eOil level is measured from the top of the tube with the fork compressed and the spring removed. A spring that is the correct length still needs the preload spacer checked, since installed length is what sets sag. Öhlins states the oil and the air-gap for this application — both are part of the setting, not a detail.\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.
