DescriptionThe whole story▼

Öhlins part number 61104-69 is a shock absorber spring rated at 170 N/mm, 130 mm long with a 57 mm inner diameter. Adding a pillion or luggage changes the load enough that the standard rate stops working.

Key Features

  • Free length 130 mm
  • Inner diameter 57 mm
  • Measured spring rate 170 N/mm

Why the Rate Holds

The wire is progressively wound where the application calls for it and straight where it does not. Production is Öhlins' own in Sweden, and the tolerance on the rate is what separates these from a generic replacement. Service parts stay available for years after a part number leaves the current price list.

The Numbers That Matter

Öhlins holds the free length at 130 mm and the inner diameter at 57 mm across this rate range, so moving up or down a rate changes nothing about the installation.

What This Rate Does

A firm rate keeps the fork high in its stroke under braking, which preserves the geometry when the front is loaded hard. This end of the range suits heavier riders, two-up use, or a machine ridden hard enough that fork dive becomes the limit. Firm rates trade some small-bump comfort for support — the right trade on a good surface at speed. Ride quality on the road is decided by rate first and damping second.

What the Rear Spring Decides

Öhlins sells rear springs separately precisely because rider weight varies more than machine weight does. Preload adjusts sag within a rate; it does not change the rate, and no amount of it will rescue a spring that is wrong. A rear spring is the cheapest part of the suspension and the one that decides the most.

Applications

Rather than a model list, use the measurements: a fork that accepts this diameter and length is a candidate, and the rate follows from rider weight. This is a service part in the proper sense — it wears, it settles, and replacing it restores what the suspension was designed to do. Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units.

What Fitting Involves

Öhlins states an air gap for this application, and that figure is part of the setting rather than a detail. The springs come powder-coated and need no preparation before they go in. Öhlins part numbers are stamped on the packaging rather than the spring, so keep the label with the setup notes.

Road Approval

Road approval: springs are not separately type-approved in Germany because they substitute a part that is already homologated with the fork. Model-specific documents, where they exist, are named above.

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.
