How Öhlins Makes Them

Materials read unremarkably on paper — aluminium, steel, nitrogen — and the difference lies in how precisely they are made. Seals are specified for temperature stability rather than for the lowest unit cost. Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted.

Size and Rate

At 466 mm free length and 41 mm inner diameter, this spring is dimensionally interchangeable with anything of the same size — the rate is what makes it a different part.

Where This Rate Belongs

Comfort and grip come from the spring moving early; this is the end of the range where that happens. This is the end of the range where small-bump compliance matters more than resistance to diving. On a machine ridden solo and mostly on the road, softer is often the honest choice. 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.

Applications

Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units. A workshop will pick this spring from its dimensions and the rider's weight, not from a fitment table. A spring is one of the few suspension parts that is genuinely interchangeable: same bore, same free length, and it goes in.

Installation

Öhlins states the oil and the air-gap for this application — both are part of the setting, not a detail. Torque the fork caps to the manufacturer's figure; the springs change nothing about the assembly torque. Öhlins part numbers are stamped on the packaging rather than the spring, so keep the label with the setup notes.

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.
