Spring rate is the single largest variable in how a front end behaves, and it is the one thing no damping adjuster can compensate for.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMeasured spring rate 9.0 N\/mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 08445-90\u003c\/li\u003e\n\u003cli\u003eFree length 390 mm\u003c\/li\u003e\n\u003cli\u003eSupplied as a pair\u003c\/li\u003e\n\u003cli\u003eInner diameter 43 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the Rate Holds\u003c\/h2\u003e\u003cp\u003eService parts stay available for years after a part number leaves the current price list. Seals are specified for temperature stability rather than for the lowest unit cost. Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly.\u003c\/p\u003e\u003ch2\u003eDimensions\u003c\/h2\u003e\u003cp\u003eThe 43 mm bore and 390 mm length are the two figures that decide whether it physically fits; 9.0 N\/mm decides whether it suits the rider.\u003c\/p\u003e\u003ch2\u003eWhat This Rate Does\u003c\/h2\u003e\u003cp\u003eA middle rate balances support against compliance, which is why Öhlins uses it as the baseline. Mid rates suit a solo rider on a road-going machine with occasional spirited use. A mid rate balances support under braking against compliance over the surface, which is why it is the usual starting point. Ride quality on the road is decided by rate first and damping second.\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. Öhlins builds springs to dimensions rather than to model lists, so the question is always the same: does the diameter fit, does the length fit, and is the rate right for the rider? A workshop will pick this spring from its dimensions and the rider's weight, not from a fitment table.\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003eWork on both legs in one session so the fork stays symmetrical. Spring preload spacers may need adjusting to keep the installed length correct. The fork legs come off, the springs are swapped and the oil level is reset — half a day in most workshops.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: a spring is a like-for-like replacement of a wear part and carries no separate type approval. Where Öhlins states an approval for a particular motorcycle, it is named under Applications.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins components deliver what they promise once they are fitted and set up properly.
