Model Description


EVO 300 4T MY 2025

The EVO Factory models represent the racing EVOlution of Beta’s trial bikes and, as usual, are being launched on the market just before the start of the racing season, ready to compete at the highest levels.

The World Championship with George Hemingway (TR3 125), alongside the excellent placings of Matteo Grattarola (TRIALGP) and Andrea Sofia Rabino (GP WOMEN), as well as the respective victories in national championships, reaffirm the excellent rideability and performance introduced by the model.
The Model Year 2025 bike receives a major upgrade to the suspension, with the introduction of a new, larger diameter fork which provides major benefits both in use and in the ability to customise the settings.
