DescriptionThe whole story▼

The GasGas EC 250F in its 2024–2025 form takes Öhlins part number DMX 1309. What a rider feels as a lack of rear grip is usually a damper that has stopped keeping up.

Key Features

  • Built to 457 mm installed length
  • Stroke: 137 mm
  • Model-specific fitment for the GasGas EC 250F (2024–2025) — no modification required

Fitted to the EC 250F

Enduro machines spend hours at low speed over roots and rock before the first fast section arrives, and the suspension has to be plush there without collapsing later.

How Öhlins Builds It

Every unit is dyno-tested against the curve held for its part number, not sampled from a batch. Service parts stay available for years after a part number leaves the current price list. Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted.

Damping and Adjustment

1304 is the Öhlins oil specification for this number. At 457 mm it matches the standard unit's installed length exactly. With 137 mm of stroke the damping curve has to do its work in a short distance. Öhlins publishes a baseline setting for each part number, which is the sensible starting point. Compression and rebound are adjusted independently, so support under load can be set without changing how fast the wheel returns.

About the TTX Flow DV Range

Ride height and preload are set with the spring collar; the damper itself is length-fixed for the linkage it was designed around. Öhlins supplies a baseline setting for each part number, established on the machine it is listed against. Öhlins builds the TTX Flow with a 46 mm piston and an external reservoir sized for the oil volume a moto actually needs.

Fitment and Compatibility

The fitment stated here is the GasGas EC 250F in its 2024–2025 form, under Öhlins part number DMX 1309. Öhlins lists no other machine against this number, so it is not a unit that can be adapted to a neighbouring model. Öhlins notes for this application: 06310- spring series. Preload adjuster 15000-02 fits this shock. *Replaces DMX 0309*

Road Approval

Road approval: unclear. There is no published German approval for this part on the GasGas EC 250F, and we would rather tell you that than imply one exists.

Fitting and Setup Service

Fitting matters as much as the part. We are an authorised Öhlins service centre and carry out installation, servicing and setup ourselves — get in touch and we will arrange it alongside your order.
