DescriptionThe whole story▼

The Beta RR 4T 480 Racing in its 2020–2025 form takes Öhlins part number DMX 1305. A factory shock is set for an average rider on an average road, and few riders are either.

Key Features

  • 131 mm of damper stroke
  • Direct fitment on the Beta RR 4T 480 Racing (2020–2025)
  • Length 474 mm, set for this chassis

The TTX Flow DV in Detail

The adjusters meter flow directly rather than bleeding it off, which is why a single click produces a change a rider can feel. Öhlins supplies a baseline setting for each part number, established on the machine it is listed against. 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.

Why This Machine Needs It

At 480 cc the RR 4T 480 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. This part number spans model years 2020 to 2025; earlier and later generations take different numbers. On a supersport machine, front-end feel under braking is what the rider trusts, and damping is what provides it.

Materials and Manufacture

Production has stayed in Sweden since the company was founded in 1976. The eyelets carry spherical bearings rather than rubber bushes, so the damper is not fighting its own mounting. Service parts stay available for years after a part number leaves the current price list.

Damping and Adjustment

The available stroke of 131 mm sets how much wheel travel the shim stack has to control. Öhlins specifies 474 mm here, so ride height stays as the factory set it. 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. A single click produces a change most riders can detect, which is not true of every adjustable damper.

Fitment and Compatibility

What follows applies to the Beta RR 4T 480 Racing built 2020–2025, which is the machine DMX 1305 is listed for. 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- & 06451- spring series. Preload adjuster 15000-02 fits this shock. *Replaces DMX 0305*
