DescriptionThe whole story▼

This is the Öhlins FFX 2304, released for the KTM 450 XCF-W as built between 2024 and 2025. A fork that dives unevenly under braking makes the 450 XCF-W feel vague long before grip runs out.

Key Features

  • Direct fitment on the KTM 450 XCF-W (2024–2025)
  • Öhlins spring 08765-43 included
  • Spring rate 4,3 N/mm, set against this machine's weight
  • Stroke: 298 mm

About the RXF 48 S Range

Öhlins built the RXF 48 for off-road racing: 48 mm tubes, separate compression and rebound adjustment, and in the S specification a coil spring rather than an air chamber. A coil spring holds its rate as the fork heats; an air spring does not, and that is the central argument for the conversion. Öhlins supplies the RXF 48 S with springs matched to the machine, and alternative rates are catalogue items.

Damping and Adjustment

Damping was developed with 1330 in the unit. 298 mm is the stroke Öhlins specifies against the 450 XCF-W's ratio. Öhlins fits a 4,3 N/mm spring to this number; riders far from average weight should expect to change it. Öhlins identifies the spring as 08765-43. Compression and rebound adjusters sit at the fork tops and work independently. Settings are marked in clicks from fully closed, so they can be recorded.

Materials and Manufacture

Every Öhlins dealer can re-valve the unit, because the shim stack is a documented, serviceable assembly. Materials read unremarkably on paper — aluminium, steel, nitrogen — and the difference lies in how precisely they are made. Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted.

What This Means on the 450 XCF-W

At 450 cc the 450 XCF-W makes enough torque to load the rear hard on corner exit, and the damper has to keep the wheel in contact while that happens.

Fitment and Compatibility
