How Öhlins Makes Them
Production is Öhlins' own in Sweden, and the tolerance on the rate is what separates these from a generic replacement. Öhlins winds, heat-sets and then measures every spring individually — the rate on the label is the rate you get. Shafts are hardened and surface-treated so the seal has a consistent surface to run against.
The Numbers That Matter
Dimensionally this is a 46 mm × 200 mm spring; within that envelope Öhlins offers a range of rates, and this one is 58 N/mm.
Where This Rate Belongs
A 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.
How a Rear Spring Works
Öhlins sells rear springs separately precisely because rider weight varies more than machine weight does. Rear spring rate sets ride height and static sag, and those two decide the chassis attitude before any damping click matters. Two riders 20 kg apart on the same motorcycle genuinely need different rates, not different clicks.
Applications
Öhlins offers rates in defined steps so a change can be made in one direction at a time rather than by guesswork. Öhlins lists no fixed model here — the spring is defined by its measurements, and any fork with matching dimensions can take it. This spring is chosen by its dimensions rather than by motorcycle model: check inner diameter, free length and rate against the fork it is going into.
Fitting
Work on both legs in one session so the fork stays symmetrical. Note the original oil level before draining — it is a useful reference even when Öhlins specifies its own. The job needs no special tools beyond a fork spring compressor and a measuring rod for the oil level.
Road Approval
Road approval: no separate certificate. The spring changes the rate, not the construction of the fork, and is treated as a service part.
Fitting and Setup Service
Öhlins components deliver what they promise once they are fitted and set up properly. As an authorised Öhlins service centre we do exactly that in house — installation, service and setup. Simply ask if you would like us to take care of it.
