We Are The Difference
Beta USA is proud to announce the 2025 Evo Factory range. Further refinement of the Evo Factory models points them closer to perfection as ever. Our engineers in Italy continue to work with the World Trial team riders to provide feedback on improvements on both the chassis and the engine to provide what is said to be the “Gold Standard” of trial.
