Beta is launching the new EVO My 2025 with a continued development that has helped the EVO line in becoming the best-selling trials model in the world. Beta engineers have continued the development of the EVO range for My 2025 with an all-new suspension package that improves the overall balance and rideability of the line.
The EVO range is one of the most extensive and continues to offer a total of six different models, each with its own character and able to meet the needs of all riders, raising the potential and level of enjoyment that each experiences. Proof is the significant presence of EVO models in the paddocks of every form of racing.
EVO 125 2STR
The smallest homologation-ready bike in the range. Light and agile, this is perfect for young riders moving up from lesser classes and making their first forays into more serious competitions. The benchmark bike in its class. The engine delivers enough performance to overcome any obstacle in safety, while still being fun and easy to handle.
EVO 250 2STR
This is the ideal bike for riders looking for an agile and easily controllable 2-stroke, with a more docile temperament and with slightly less power and torque than the range-topping model. The Evo 250 is ideal for the amateur looking for class-beating performance combined with precisely manageable power and impeccable Rideability.
EVO 300 2STR
The 300 2 Str is the range-topping model in the Evo family. A bike for lovers of big capacity engines with impressive torque at all engine speeds, and the perfect base for competing even at pro levels. The frame and the engine have been developed to maximise the ability of the bike to overcome even the most challenging obstacles and the most technically difficult trials. The ideal solution for expert riders looking for bike with class-beating performance, but which is intuitive and easily manageable from the moment you get into the saddle.
New Features for the Entire Range:
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. The end-of-travel buffering has also been optimised with the greatest focus on correct support during descent, to guarantee maximum grip of the front tyre on the terrain.
The adoption of all the most recent new additions to the preceding Model Years are also confirmed.
