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.

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.

Features may include:

  • Competition tires with numerous national championships to their credit. Designed for professional and amateur trial riders alike. This tire complements the precision & handling of the EVO range.
  • Radiator Grill designed to optimize airflow directed at radiator with more protective surface to prevent damage from falls, branches, or rocks.
  • Tank cover designed with a shape that flows with frame and allows better cable management for a clean and more orderly look.
  • Domino Grips help to achieve maximum control and comfort providing solid grip.
