DescriptionThe whole story▼

Part number FFX 2304 is what Öhlins supplies for the KTM 300EXC, model years 2024–2026. Front-end feel is a damping problem before it is a geometry problem.

Key Features

  • Spring part number 08765-43 fitted
  • Listed by Öhlins for the KTM 300EXC (2024–2026) and no other machine
  • 298 mm working stroke
  • Fitted spring rate 4,3 N/mm, chosen by Öhlins for the 300EXC

Why This Machine Needs It

This part number spans model years 2024 to 2026; earlier and later generations take different numbers.

About the RXF 48 S Range

Air springs need checking before every ride and change their rate as they heat; a coil does neither. For a rider who wants the fork to feel the same on the last lap as on the first, that is the whole argument. A coil spring holds its rate as the fork heats; an air spring does not, and that is the central argument for the conversion.

Construction and Material Quality

Fork springs are separate catalogue items and can be changed without dismantling the cartridge. Materials read unremarkably on paper — aluminium, steel, nitrogen — and the difference lies in how precisely they are made. The unit is rebuildable: seals, shims and oil are catalogue items, not a reason to buy a new one.

Front-End Performance

The fitted spring is 08765-43, and Öhlins lists neighbouring rates under their own numbers. The unit measures 940 mm installed, which is the dimension the 300EXC's linkage expects. 4,3 N/mm is the rate Öhlins selected after testing on the 300EXC. 298 mm is the stroke Öhlins specifies against the 300EXC's ratio. Settings are marked in clicks from fully closed, so they can be recorded. The range is wide enough that both ends of it are usable rather than theoretical.
