RR RACE 390 4T MY 2025

It’s RACE time!


Quick, precise and lean, just like real racing bikes, Beta's new race-ready RR models are changing their name and getting straight to the point, providing all off-road lovers with exceptional performance and zero-compromises.

The 2025 RR Race bikes represent the race-ready versions of Beta's newly-introduced X-Pro models, with a series of modifications to the engine, suspension, and frame, making them ideal for providing their best on the track. Designed for both low and high-speed courses, the Race models will provide riders with the confidence and Rideabiility that only Beta can deliver.

Take a look at all the new features and characteristics which set the models apart.

New Features

For Model Year 2025 there are a range of new features for the entire two- and four-stroke range, while others are specific to the individual models:

New features for all models

  • New Ergal alloy footpegs: redesigned to ensure maximum control at all times and no loss of contact with the bike, the RR Race 25 models are fitted with new ergal racing footpegs with steel pins which are interchangeable; these are narrower than in the past to facilitate movement of feet, but better in terms of grip.
  • Front brake calliper: a lighter and higher-performance Nissin calliper compared to the previous component appears on the new Race models; this helps emphasise the bike's handling, while maintaining braking power, progressiveness and modulation.
  • Larger rear wheel axle: the rear wheel axle size has been increased 2mm in diameter, for a total of ø 22mm. This new axle provides greater stiffness and torsional resistance, resulting in a bike that is always precise and well steered, even in the most violent accelerations. The rear swingarm has also been update to accommodate the new axle.
  • Mapping switch on the handlebars: the mapping switch button is no longer located in the traditional position behind the steering tube: it is now on the handlebars, inside the bumper, maintaining family feeling with the X-PRO models. Both the mapping switch and the Traction Control button for the four-stroke model is housed here.
  • Bodywork: the new superstructures recently introduced on the X-PRO have been incorporated in the 2025 RR Race with an aggressive and flashy new appearance, generating a complete restyling of the bike. The headlight mask, tank panels, sides and rear tail have been redesigned by Beta. The mask has a tapered design, while the tail and the tank panels are sleek and well connected, maintaining simple, tool-free access to the air filter, while retaining the push button seat removal.

On all two-stroke models, The oil injection is not included on Race models to reduce the overall weight of the bike however it can be added as an option. (available in the Factory Parts catalogue)

For some displacements in the two-stroke range, new engine features have been added:

Engine - RR Race Four-Stroke

All four-stroke Race models receive new crankcases, derived from the engine used on the RX 450. The main benefit deriving from the use of this new component lies in the smaller size and lighter weight compared to the previous model.

Aesthetically sleeker, the new four-stroke Race MY 2025 engine now leaves more space for the exhaust passage as well, facilitating installation, removal or replacement operations.

Racing Components – Entire Range

Unchanged, however, is the tried and tested suspension package and the special components of Beta's race-ready version:

  • 48 mm Kayaba AOS closed cartridge fork: Anodised internal parts and the treatments administered to the materials minimise sliding friction, while adjustable compression and rebound damping let each rider find the perfect customisation of the setting.
  • Kayaba C46 RCU shock: The KYB shock can be seen as a gold standard in the racing scene in terms of its ability to absorb the roughness of the terrain, the level of traction transferred to the rear wheel and the consistency of performance even under particularly heavy use. Adjustable for preload, compression (high and low speed) as well as rebound ensures riders can dial the suspension to his or her liking.
  • Quick release front axle: immediately recognisable by the red anodised alloy release lever, this component is crucial for saving precious seconds in a race when you need to change a tyre.
  • Reinforced handguards: the handguards feature a two-component material mould, and not only give the bike a racing look but also make them especially hard-wearing in even the roughest off-road use.
  • Rear sprocket with anodised aluminium core and steel toothing by ZF SPROCKETS: top-class performance, lightness and strength – the benefit of light weight with steel teeth for long life.
  • Race seat: with non-slip cover and document holder pocket for unparalleled grip, comfort and practicality.
  • Anodised black gear lever and rear brake pedal.
  • Gearbox oil filler cap, engine oil filler cap and oil filter cap anodised red aluminium.
  • Chain tensioner blocks in red ergal alloy.
