DescriptionThe whole story▼
The GasGas EX 450F in its 2021–2023 form takes Öhlins part number FFX 1201. A fork that dives unevenly under braking makes the EX 450F feel vague long before grip runs out.
Key Features
- Öhlins fits a 4,7 N/mm spring to this application
- Ships with spring 02428-47
- Bolts to the GasGas EX 450F (2021–2023) using the standard mounting points
- Damper stroke 297 mm
The RXF 48 S in Detail
The coil holds its rate as the fork heats and needs no pressure check between motos. 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.
Damping and Adjustment
297 mm is the stroke Öhlins specifies against the EX 450F's ratio. Length is 950 mm and is not adjustable on this number. Rate as supplied is 4,7 N/mm, matched by Öhlins to this machine rather than to the platform. Öhlins supplies spring 02428-47 with this unit. The range is wide enough that both ends of it are usable rather than theoretical. Settings are marked in clicks from fully closed, so they can be recorded.
Setting It Up for the EX 450F
The 2021–2023 generation kept the same chassis dimensions throughout, so one Öhlins number serves the whole run.
Construction and Material Quality
The Öhlins part number is stamped on the unit, so its specification can be looked up years later. Öhlins applies a low-friction coating to the sliding surfaces on most fork numbers, which reduces stiction. Öhlins machines its own critical components instead of buying them in, and the tolerances are where the money goes.
Fitment and Compatibility
This listing covers Öhlins part number FFX 1201 for the GasGas EX 450F, 2021–2023. Because the settings are model-specific, fitting it to a related machine would mean running the wrong specification.
Road Approval
Road approval: no documented status for the GasGas EX 450F. Get in touch before ordering if the machine is to stay road legal.
