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\u003eInner diameter 70 mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 06774-09\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 45 N\/mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003e172 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eFree length 290 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eÖhlins winds, heat-sets and then measures every spring individually — the rate on the label is the rate you get. Rates are offered in defined steps, so a change can be made in one direction at a time. Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eÖhlins holds the free length at 290 mm and the inner diameter at 70 mm across this rate range, so moving up or down a rate changes nothing about the installation.\u003c\/p\u003e\u003ch2\u003eChoosing 45 N\/mm\u003c\/h2\u003e\u003cp\u003eIf you are unsure and close to average weight in full kit, this is the sensible starting point. A mid rate balances support under braking against compliance over the surface, which is why it is the usual starting point. Mid rates suit a solo rider on a road-going machine with occasional spirited use. 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\u003eA shock absorber spring carries the whole rear of the machine through a linkage that multiplies its rate several times over — which is why the number on the spring looks so much larger than a fork rate. Because the linkage is progressive on most modern machines, a small change in rate moves the sag more than riders expect. The rear spring carries the rider, the pillion and the luggage; the front carries only part of it.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eThere is no model list for this size because the spring is a dimensional part: it fits whatever fork it physically fits. Ask us with the machine and rider weight and we will tell you which rate in this size to take. 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\u003eFitting\u003c\/h2\u003e\u003cp\u003eA spring that is the correct length still needs the preload spacer checked, since installed length is what sets sag. Öhlins supplies a setting sheet with the springs; the numbers on it assume the specified oil. Once fitted, ride the machine before making damping changes: the new rate alters what the clicks do.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: none is issued for springs as such — they replace an existing component of the same function. Any model-specific approval is listed under Applications.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting matters as much as the part.
