2025 Beta EVO 125 2-Stroke

The Evo 125 and 200 models are the ideal trials model for those younger riders or adults starting out in the sport. Their softer power still provides plenty of torque with a chassis that is stable and inspiring. The two models are very similar in design with the 200 providing a small amount of added torque.

These full size models share the same chassis specifications as the 250 and 300 versions but arrive with a chrome-tube front fork and smaller engines. These models are perfect for riders starting out due to their forgiving power delivery that will not overwhelm the rider. The Evo 200 is the only one in the class and offers a light-weight feel but with added torque.

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.
