Quick, precise, and lean best describe Beta's new RR Race models for the 2025 season. With a new, shortened name to simply “RR Race” to get straight to the point. The 2025 RR Race lineup provides riders with a model whose performance is second to none.

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 Rideability that only Beta can deliver.

As it has repeatedly demonstrated, Beta believes in the potential of young people, and the manufacturer has once again chosen to highlight this with the new RR Race Model Year 2025 bikes, making a series of changes to the small 125cc engine. The purpose of this intervention was to increase the power delivered by the 125 two-stroke along the entire delivery curve, intensifying the maximum peak horsepower available. This result has been made possible by a new piston and new cylinder head. Thanks to these changes the engine is more reactive, powerful and throaty, increasing even further the explosiveness of the maximum performance.

The new 125cc engine therefore now has a greater range of use than in the past, where previous improvements had already raised the bar for the model, increasing power at high engine speeds without losing torque in the low end.
