A rear spring matched to rider and load keeps the chassis attitude where the factory intended it.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eFree length 290 mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003e156 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00180-71\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 32 N\/mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eRates are offered in defined steps, so a change can be made in one direction at a time. Every unit is dyno-tested against the curve held for its part number, not sampled from a batch. 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\u003eAt 290 mm free length and 46 mm inner diameter, this spring is dimensionally interchangeable with anything of the same size — the rate is what makes it a different part.\u003c\/p\u003e\u003ch2\u003eChoosing 32 N\/mm\u003c\/h2\u003e\u003cp\u003eThis is the end of the range where small-bump compliance matters more than resistance to diving. On a machine ridden solo and mostly on the road, softer is often the honest choice. Comfort and grip come from the spring moving early; this is the end of the range where that happens. 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\u003eProgressive springs change rate through the stroke, which suits machines with little travel and a lot of load. Rear spring rate sets ride height and static sag, and those two decide the chassis attitude before any damping click matters. Preload adjusts sag within a rate; it does not change the rate, and no amount of it will rescue a spring that is wrong.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eRather 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. There is no model list for this size because the spring is a dimensional part: it fits whatever fork it physically fits. Öhlins lists no fixed model here — the spring is defined by its measurements, and any fork with matching dimensions can take it.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eSpring preload spacers may need adjusting to keep the installed length correct. The job needs no special tools beyond a fork spring compressor and a measuring rod for the oil level. Oil level is measured from the top of the tube with the fork compressed and the spring removed.\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.
