Information

2025 Beta EVO 300 4-Stroke

For those who like thumpers, the Evo 300 4 stroke is the bike of choice. Over 8 lbs. lighter than the other brands' 4 stroke as well as a tighter turning radius, the Evo 300 4 stroke is known for being a more gentle bike to ride while also being "Whisper quiet". The bulletproof engine design is easy to work on and will provide years of trial fun!

The 4-stroke model also boasts an engine capacity of 300 cc, and strikes the perfect balance between performance, tractable engine power and overall usability. This engine embraces a completely different approach to riding than its 2-stroke siblings. With plenty of torque and linear, extremely progressive power delivery, this is the perfect bike for the amateur looking for a machine suitable for less challenging competitive use and motorcycle mounting climbing.

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.
