Why the Rate Holds
Rates are offered in defined steps, so a change can be made in one direction at a time. The finish is applied after setting, which means the coating does not affect the rate. 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
Free length 170 mm, inner diameter 57 mm, rate 150 N/mm — those three figures define the part completely.
Where This Rate Belongs
Firm rates trade some small-bump comfort for support — the right trade on a good surface at speed. If the suspension bottoms out or the geometry collapses under load, this is the direction to go. This end of the range suits heavier riders, two-up use, or a machine ridden hard enough that fork dive becomes the limit. Ride quality on the road is decided by rate first and damping second.
How a Rear Spring Works
Adding a pillion or luggage changes the rear load enough that the standard rate stops working properly. The damper can only control the spring it is given; the wrong rate makes every setting a compromise. Static sag at the rear sets the whole chassis attitude — get it wrong and the front geometry goes with it.
Applications
Öhlins offers rates in defined steps so a change can be made in one direction at a time rather than by guesswork. There is no model list for this size because the spring is a dimensional part: it fits whatever fork it physically fits. Rate is the variable that depends on the rider, not on the machine. Two people on the same bike may well want two different numbers.
Installation
Note the original oil level before draining — it is a useful reference even when Öhlins specifies its own. Öhlins states the oil and the air-gap for this application — both are part of the setting, not a detail. Any suspension workshop can fit these; the fork does not need to leave the bike for long.
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
Fitting matters as much as the part. We are an authorised Öhlins service centre and carry out installation, servicing and setup ourselves — get in touch and we will arrange it alongside your order.
