DescriptionThe whole story▼

The Öhlins DMX 1304 exists because the Beta RR 4T 350 Racing (2020–2025) needed its own settings, not a shared set. What a rider feels as a lack of rear grip is usually a damper that has stopped keeping up.

Key Features

  • Model-specific fitment for the Beta RR 4T 350 Racing (2020–2025) — no modification required
  • Damper stroke 131 mm
  • 474 mm between mounting eyes

Setting It Up for the RR 4T 350 Racing

Supersport chassis are stiff and short, which leaves the suspension doing almost all the compliance work. This part number spans model years 2020 to 2025; earlier and later generations take different numbers. At 350 cc the RR 4T 350 Racing makes enough torque to load the rear hard on corner exit, and the damper has to keep the wheel in contact while that happens.

Where This Sits in the Öhlins Line-up

Öhlins builds the TTX Flow with a 46 mm piston and an external reservoir sized for the oil volume a moto actually needs. Compression and rebound run as separate, permanently pressurised circuits — the twin-tube principle — so neither can starve the other on a fast series of hits. Service intervals are short by road standards — this is a racing damper, and Öhlins expects it to be opened regularly.

Construction and Material Quality

The unit is rebuildable: seals, shims and oil are catalogue items, not a reason to buy a new one. Materials read unremarkably on paper — aluminium, steel, nitrogen — and the difference lies in how precisely they are made. Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted.

How It Behaves on the Road

Öhlins specifies 474 mm here, so ride height stays as the factory set it. The damper moves 131 mm from full extension to full compression. 1304 is the Öhlins oil specification for this number. Compression and rebound are adjusted independently, so support under load can be set without changing how fast the wheel returns. Adjustment is by click rather than by feel, so a setting can be written down and returned to.

Fitment and Compatibility

Öhlins part number DMX 1304 is the correct number for the Beta RR 4T 350 Racing as built 2020–2025. It is model-specific rather than universal: length, stroke and valving are all set for this chassis. Öhlins notes for this application: 06310- & 06451- spring series. Preload adjuster 15000-02 fits this shock.
