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.
The highlights of the new Factory MY 25 models, in terms of the ENGINE and FRAME AND SUSPENSION, are as follows:
4-stroke
The 4-stroke Factory variant also benefits from a series of upgrades relative to the standard EVO version. The electronic control unit receives a higher power rating, which translates to improved spark stability and improved combustion at all engine speeds. In order to provide an outlet for the greater available power, the EVO Factory 4-stroke is also equipped with a lighter weight and higher performance titanium silencer.
FRAME AND SUSPENSION
In terms of the frame and design, the new Evo Factory My 2025 differs from the standard version as follows:
The development of the front fork has been guided by the desire to create a product with a more rigid, yet simultaneously lighter, structure: this has been achieved through the use of a special steel which has allowed the thickness of the fork rod to be reduced without compromising its strength, and to achieve a greater internal diameter, which is useful in terms of hydraulic management.
The new and greater internal volume available has allowed the use of components of greater diameter, able to manage greater hydraulic flow rates, which provide a more progressive response to compression, as well as greater precision in customisation of the settings.
Compared to the EVO, the new forks on the Factory model are specifically calibrated for racing use, which combines perfectly with the different cartridge, longer than the standard version, which significantly improves progressiveness or end-of-travel compression.
The Evo Factory 25 is confirmed to have gold stanchions, which provide the model with both aesthetic and functional benefits. The striking colour is the result of TiN treatment which provides excellent low-friction properties to the fork.
The single shock, a benchmark in its category, receives a new aluminium body for 2025 to replace the heavier steel of its predecessor, helping reduce the overall weight of the bike.
The new suspension features guarantee a more progressive response for the bike in compression and improved rebound management, simplifying “floating” between rocks and the ability to absorb significant impacts, such as landing after jumping large obstacles.
