Overview:
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.
After making its debut on the previous 2024 300 Race model, the 250 now incorporates the new cylinder head with dual spark plug, improving the specifications of the engine. The delivery is more linear, and despite the increase in maximum power, the bike's docility is significantly greater. The use of the dual spark plug indeed provides numerous benefits:
» It offers a cleaner-burning ignition along with an improvement in fuel consumption. This translates into greater carburation stability at all engine speeds, and a broader power delivery under all grip conditions.
» The engine's range of use is further extended, as both greater torque and more power are available.
» The two spark plugs are managed with a completely separated electrical system. This means that, if one of the spark plugs should burn out, the engine will still be able to run, although with less efficiency, allowing the race or off-road session to be completed.
