DescriptionThe whole story▼

Öhlins lists part number DMX 0309 for one machine: the GasGas EC 250 built 2024–2026. A factory shock is set for an average rider on an average road, and few riders are either.

Key Features

  • Built for the GasGas EC 250 (2024–2026); fits without modification
  • Öhlins length specification: 457 mm
  • 137 mm of travel at the damper

Where This Sits in the Öhlins Line-up

A motocross track feeds the rear damper the same impact twenty times a lap; what matters is whether the twentieth feels like the first, and that is exactly what the pressurised circuits protect. Öhlins builds the TTX Flow with a 46 mm piston and an external reservoir sized for the oil volume a moto actually needs. Ride height and preload are set with the spring collar; the damper itself is length-fixed for the linkage it was designed around.

Materials and Manufacture

The unit is rebuildable: seals, shims and oil are catalogue items, not a reason to buy a new one. Seals are specified for temperature stability rather than for the lowest unit cost. Every unit is dyno-tested against the curve held for its part number, not sampled from a batch.

Damping and Adjustment

At 457 mm it matches the standard unit's installed length exactly. Damper stroke comes to 137 mm on this number. The recommended oil is 1304; using something else changes the damping the shim stack was set for. The adjuster range is usable end to end rather than only around the middle. Öhlins publishes a baseline setting for each part number, which is the sensible starting point.

Why This Machine Needs It

The 2024–2026 generation kept the same chassis dimensions throughout, so one Öhlins number serves the whole run. 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. At 250 cc the EC 250 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

Part number DMX 0309 and the GasGas EC 250 (2024–2026) belong together; other model years take other numbers. Because the settings are model-specific, fitting it to a related machine would mean running the wrong specification. Öhlins notes for this application: 06310- spring series. Preload adjuster 15000-02 fits this shock. *Replaced by DMX 1309*

Road Approval

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

Fitting and Setup Service

We are an authorised Öhlins service centre, so the installation does not have to be your problem: we fit and set up Öhlins components in our own workshop. Ask us when you order and we will include the work.
