Model Description


EVO FACTORY 4T 300

The EVO Factory models represent the racing EVOlution of Beta’s trial bikes and, as usual, are being launched on the market in February, just before the start of the racing season, ready to compete at the highest levels.
George Hemingway’s World Championship (TR3 125), alongside the excellent results of Matteo Grattarola (TRIALGP) and Andrea Sofia Rabino (GP WOMEN), and in addition to the respective victories in national championships, reaffirm the excellent driveability and performance provided by the Factory model.
For Model Year 2024, some updates have been made which increase the model’s refinement, while maintaining its racing pedigree.
