DescriptionThe whole story▼

The Kawasaki KX450F of 2019–2026 has its own Öhlins part number, and this is it: FFX 2204. The front end is where a rider's confidence is won or lost on the KX450F.

Key Features

  • Damper stroke 299 mm
  • Model-specific fitment for the Kawasaki KX450F (2019–2026) — no modification required
  • Spring rate 4,7 N/mm, set against this machine's weight
  • Ships with spring 02428-47

Materials and Manufacture

Seals are specified for temperature stability rather than for the lowest unit cost. Materials read unremarkably on paper — aluminium, steel, nitrogen — and the difference lies in how precisely they are made. Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly.

The RXF 48 S in Detail

The fork is built for racing use and expects racing service intervals — oil and seals at regular hour counts. Öhlins supplies the RXF 48 S with springs matched to the machine, and alternative rates are catalogue items. The S in RXF 48 S stands for the spring conversion: a coil spring replaces the air chamber the standard fork uses.

How the Fork Works

Öhlins identifies the spring as 02428-47. Damping was developed with 1330 in the unit. Öhlins builds it to 946 mm between the eyes for this chassis. The spring is wound to 4,7 N/mm, and alternative rates are catalogue items. Compression and rebound adjusters sit at the fork tops and work independently. The range is wide enough that both ends of it are usable rather than theoretical.

The KX450F in Particular

The 2019–2026 generation kept the same chassis dimensions throughout, so one Öhlins number serves the whole run.
