This is the change a suspension technician makes first, before touching a single click.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e280 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 08789-42\u003c\/li\u003e\n\u003cli\u003eInner diameter 38.2 mm\u003c\/li\u003e\n\u003cli\u003eFree length 423 mm\u003c\/li\u003e\n\u003cli\u003eSupplied as a pair\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 4.2 N\/mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManufacture and Tolerance\u003c\/h2\u003e\u003cp\u003eSeals are specified for temperature stability rather than for the lowest unit cost. Each spring is set before it is measured, so it will not settle and lose rate in service. Rates are offered in defined steps, so a change can be made in one direction at a time.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eDimensionally this is a 38.2 mm × 423 mm spring; within that envelope Öhlins offers a range of rates, and this one is 4.2 N\/mm.\u003c\/p\u003e\u003ch2\u003eChoosing 4.2 N\/mm\u003c\/h2\u003e\u003cp\u003eExpect more sag and more movement — that is the point, not a fault. At this rate the fork sits deep in its travel under load, which is exactly what a long-travel chassis is designed around. Rates at this end are for long travel, light riders, or machines that need the wheel to follow the ground rather than skip over it. Road surfaces are the hardest test of a spring rate, because the fork has to cope with both a smooth stretch and a broken one.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eAny workshop with the fork or shock in front of it can answer whether this spring fits — the three figures above are all it needs. Rate is the variable that depends on the rider, not on the machine. Two people on the same bike may well want two different numbers. Where Öhlins lists this size against a particular unit, the listing is a starting point rather than a boundary.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eOnce fitted, ride the machine before making damping changes: the new rate alters what the clicks do. Set static sag after fitting; the rate is only right if the sag figure lands where Öhlins specifies. The springs come powder-coated and need no preparation before they go in.\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\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.
