Too stiff and the front loses feel over bumps; too soft and it dives under the brakes.

Service parts stay available for years after a part number leaves the current price list. 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\u003eAt 270 mm free length and 23.5 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\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eA middle rate balances support against compliance, which is why Öhlins uses it as the baseline. Rates here suit a solo rider of typical weight on a road-going machine. This is the middle of Öhlins' range — the rate most riders of average weight end up on once sag is set properly. Ride quality on the road is decided by rate first and damping second.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eWhere Öhlins lists this size against a particular unit, the listing is a starting point rather than a boundary. 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. The safest way to choose is by static sag: set the target figure, and the rate follows from whether you can reach it with preload.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eRate and preload are separate adjustments: get the rate right first, then set sag with preload. Torque the fork caps to the manufacturer's figure; the springs change nothing about the assembly torque. Check the free length against the old springs before fitting — a sagged original often measures short.\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.
