Key Features

  • Damper stroke 120 mm
  • Fitted spring: Öhlins Sold separately, see notes
  • Model-specific fitment for the Kawasaki Z900 (2017–2024) — no modification required

The Z900 in Particular

A naked bike is usually ridden on the road rather than the track, and the suspension has to cope with real surfaces. Öhlins covers the 8-year production run of this generation with a single part number, which means the mounting and the linkage stayed unchanged across it.

Construction and Material Quality

Springs come with the kit and are catalogue items in their own right if a different rate is needed. Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted. Every unit is dyno-tested against the curve held for its part number, not sampled from a batch.

Damping and Adjustment

Stroke is 120 mm, which is the travel Öhlins has to work with on this linkage. Öhlins supplies spring Sold separately, see notes with this unit. Damping was developed with 01309 in the unit. Öhlins supplies a baseline setting with the kit, established on the model it is listed for. Compression and rebound become separately adjustable, which on most standard forks they were not.

About the NIX 30 Street Range

Compression and rebound remain split between the two fork legs. Each circuit gets a whole leg to itself, so the pistons are larger and the oil velocity lower than in a design that does both jobs in one tube. Street valving favours real road surfaces over circuit use: the fork moves early and keeps the tyre loaded.

Fitment and Compatibility

What follows applies to the Kawasaki Z900 built 2017–2024, which is the machine FKS 502 is listed for. It is model-specific rather than universal: length, stroke and valving are all set for this chassis. Öhlins notes for this application: 08790-xx spring series Öhlins lists this fitment under the model designations Z900, Z900 Performance.

Road Approval

Road approval: unclear. There is no published German approval for this part on the Kawasaki Z900, and we would rather tell you that than imply one exists.

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.
