The Beta 450RX Motocross model was first introduced last year and it returns for 2025 with updated KYB suspension valving, new ECU map settings, new footpegs, a stronger battery, a reinforced subframe, an extra tooth on the rear sprocket, a new 22mm axle, and updates graphics. In this video, MXA’s Josh Mosiman explains what we’ve learned about the bike after the first few weeks of testing.
