2025 Beta 250 RR Race 2-Stroke

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:

Features may include:

  • Front brake calliper:

A lighter and higher-performance Nissin calliper that provides an improved front brake feel. This new design provides a factory-like front brake system.

  • Larger rear wheel axle:

This new axle offers greater stiffness providing the rider with better feedback while improving turning. The rear swingarm has also been updated to accommodate the new axle.

  • New Machined alloy footpegs:

redesigned for 2025 with a new shape that provides better boot traction in muddy and unstable conditions.
