DescriptionThe whole story▼

Öhlins developed FFX 2201 around the KTM 450 SX-F (2016–2026) — its weight, its linkage and its geometry. A fork that dives unevenly under braking makes the 450 SX-F feel vague long before grip runs out.

Key Features

  • Supplied with Öhlins spring 02428-47
  • Direct fitment on the KTM 450 SX-F (2016–2026)
  • 297 mm working stroke
  • Spring rate as delivered: 4,7 N/mm, matched to the 450 SX-F

The 450 SX-F in Particular

On a motocross bike the suspension is the component that decides lap time once the rider is fit enough. At 450 cc the 450 SX-F makes enough torque to load the rear hard on corner exit, and the damper has to keep the wheel in contact while that happens. Öhlins covers the 11-year production run of this generation with a single part number, which means the mounting and the linkage stayed unchanged across it.

Materials and Manufacture

Two units carrying the same part number behave the same way out of the box, which is the whole point of testing each one. The unit is rebuildable: seals, shims and oil are catalogue items, not a reason to buy a new one. Tube diameter, offset and axle clamp are all specified per model so the assembly drops into the standard yokes.

Where This Sits in the Öhlins Line-up

Air springs need checking before every ride and change their rate as they heat; a coil does neither. Air forks need a pressure check before every ride, and the RXF 48 S removes that step entirely. 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.

Front-End Performance

297 mm is the stroke Öhlins specifies against the 450 SX-F's ratio. 1330 is the Öhlins oil specification for this number. Spring part number 02428-47 is a separate catalogue item, so a rate change is inexpensive. Öhlins fits a 4,7 N/mm spring to this number; riders far from average weight should expect to change it. Each function has its own adjuster, which is what allows one change to be judged honestly. Öhlins supplies a baseline setting sheet with the fork.

Fitment and Compatibility

Öhlins part number FFX 2201 is the correct number for the KTM 450 SX-F as built 2016–2026. Öhlins releases the same number for 33 closely related machines; this listing is the KTM 450 SX-F version of that fitment. Öhlins notes for this application: 08765- spring series *Replaces FFX 1201*
