EVO 300 SS

Overview:

Beta builds the best trials bikes in the world. Our Evo 2-Stroke editions are the top seller of Trials bikes in the USA for a good reason. Evo models offer versatility for any type of Trials terrain & give all experience levels the right fit for their needs. 

Evo 250 & 300 SS:  Both models are perfect for the Clubman rider, this is a class where most current motocross and off road racers will compete in at the local level. The Evo 250 and the 300 SS (Which stands for Super Smooth) have similar power delivery characteristics with the SS model providing 20% more torque with less over-rev vs the 250.

Evo 300: This is the number one selling trial model in the world, a proven bike that can be play-ridden or competed on at the highest level of the sport. The exceptional power delivery offers a broad range power delivery as well as a very light feel while in the section. The Evo 300 is a staple in the trial world.

The main new feature for 2025 is an updated suspension.  Produced by Ollé the new fork provides an increase in torsional rigidity at the front wheel which improves the precision and ease of the bike's ride.  The new forks also allow the fork to react quicker over rocks and other section obstacles.  The Ollé rear shock is also new and like the fork it is completely adjustable as well in terms of preload and hydraulic adjustment. The shock improves on rebound management and the ability to absorb significant impacts.
