Beta USA entered the motocross world in 2021 with the introduction of their 300 RX, a 2-stroke model that provided a solid platform in design, handling, and looks. Along with the beauty of the bike, the “factory sound” of the 293cc motor was like no other. Riders quickly discovered what Beta likes to call Rideability. Rideability is the smoothness, ease of handling, and overall comfort experienced on a Beta Motorcycle. It encompasses factors such as throttle response, suspension performance, ergonomic design, and stability all contributing to a seamless ad enjoyable riding experience. Rideability is the perfect balance of power and agility that provides riders with confidence inspiring control and effortless maneuverability, resulting in a gratifying ride, no matter the conditions.

For the 2025 season, Beta is proud to release the details of the 300 RX updates to enhance its platform. Updates to the 300 include changes to the engine, chassis, and suspension. A new frame highlights the model, one that mimics that of its older 450 brother.
