The Beta EVO 4T 300 2026 is designed for riders who prefer a different approach to trials riding, one focused on traction, smooth power delivery and precise throttle control. Powered by Beta’s distinctive 297.3cc four-stroke engine, this model delivers strong low-end torque and incredibly linear power, making it ideal for riders who favour progression and grip rather than explosive response.

The EVO 4T platform combines Beta’s renowned hydroformed aluminium frame with carefully tuned suspension and a highly controllable engine character. This combination allows riders to find traction where others struggle, maintaining balance and control when navigating the most technical sections.

A two-map engine system allows the rider to quickly adapt the bike to different terrain conditions. The “Rain” map softens power delivery for slippery conditions or less experienced riders, while the “Dry” map unleashes the full potential of the engine for maximum performance.

With its unique four-stroke character, refined chassis and exceptional grip, the Beta EVO 300 4T remains one of the most distinctive trials bikes on the market.

Available now to pre-order from Road and Trials, authorised Beta dealer in Barnsley, South Yorkshire.
