Shafts are hardened and surface-treated so the seal has a consistent surface to run against. The wire is progressively wound where the application calls for it and straight where it does not.\u003c\/p\u003e\u003ch2\u003eSize and Rate\u003c\/h2\u003e\u003cp\u003eThe 46 mm bore and 200 mm length are the two figures that decide whether it physically fits; 40 N\/mm decides whether it suits the rider.\u003c\/p\u003e\u003ch2\u003eChoosing 40 N\/mm\u003c\/h2\u003e\u003cp\u003eMid rates suit a solo rider on a road-going machine with occasional spirited use. If you are unsure and close to average weight in full kit, this is the sensible starting point. This is where most riders of average weight land once static sag has been set to specification. 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\u003eA spring that has settled in service sits shorter than new, which quietly lowers the bike and steepens the steering. A rear spring is the cheapest part of the suspension and the one that decides the most. Adding a pillion or luggage changes the rear load enough that the standard rate stops working properly.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eRate is the variable that depends on the rider, not on the machine. Two people on the same bike may well want two different numbers. Öhlins offers rates in defined steps so a change can be made in one direction at a time rather than by guesswork. Selection is by measurement. If the diameter and free length match your fork, the remaining question is the rate.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eIf the fork has not been serviced recently, bushes and seals are worth replacing while it is apart. Preload spacers usually need shortening or lengthening so the installed length stays correct. A spring that is the correct length still needs the preload spacer checked, since installed length is what sets sag.\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.
