RR 125 RACE
ULTRA LIGHT AND RACE TUNED
OVERVIEW
When every second counts, every detail matters. Beta has revamped its RR Race range, bringing all the experience gained in international competition to bikes designed for the most demanding enthusiasts. These models have been developed to meet the needs of the most demanding riders, offering high performance and efficiency in competition, whilst remaining true to the Rideability philosophy. The 2027 RR Race 125 represents the pinnacle of lightweight, 2-stroke competition design. As the competition spec evolution of Beta’s X-Pro range, this model is built for riders seeking a competitive edge through agile handling and top-tier performance. For 2027, the 125 features an optimized piston designed to improve the smoothness of the overall power delivery across the rev range. To ensure maximum weight savings for the track, the automatic oil injection has been intentionally omitted, making this a pure, premix-ready machine. Paired with updated internal valve settings in the benchmark KYB suspension, a new LED headlight mask, and rugged drivetrain protections, the 125 delivers Beta’s signature Rideability, offering racers a feeling that builds ultimate confidence on the starting line.
