300 RX

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 and 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.
