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 175 mm\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 95 N\/mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21056-31\u003c\/li\u003e\n\u003cli\u003e83 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 51 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eProduction has stayed in Sweden since the company was founded in 1976. The wire is progressively wound where the application calls for it and straight where it does not. Rates are offered in defined steps, so a change can be made in one direction at a time.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 175 mm and the inner diameter at 51 mm across this rate range, so moving up or down a rate changes nothing about the installation.\u003c\/p\u003e\u003ch2\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eIf the suspension bottoms out or the geometry collapses under load, this is the direction to go. Firm rates also suit machines carrying luggage as a matter of course. This end of the range suits heavier riders, two-up use, or a machine ridden hard enough that fork dive becomes the limit. Ride quality on the road is decided by rate first and damping second.\u003c\/p\u003e\u003ch2\u003eHow a Rear Spring Works\u003c\/h2\u003e\u003cp\u003eThe rear spring carries the rider, the pillion and the luggage; the front carries only part of it. The damper can only control the spring it is given; the wrong rate makes every setting a compromise. Rear spring rate sets ride height and static sag, and those two decide the chassis attitude before any damping click matters.\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. This is a service part in the proper sense — it wears, it settles, and replacing it restores what the suspension was designed to do. If you are replacing a sagged original, measure its free length first — a tired spring often measures several millimetres short.\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003eFitting is a fork-oil job: the legs come apart, the springs go in, the oil level is set to specification. Work on both legs in one session so the fork stays symmetrical. Any suspension workshop can fit these; the fork does not need to leave the bike for long.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: springs are not separately type-approved in Germany because they substitute a part that is already homologated with the fork. Model-specific documents, where they exist, are named above.\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.
