With feedback from the factory team about the new trials range Beta have used their experience at the cutting edge of the sport to further refine the Beta Evo range for 2019, ensuring that riders of all abilities can count on the best available technology. There are three two-stroke engines: 125cc 250cc and 300cc, plus the world renowned four-stroke version, which is available as a 300cc and offers an excellent alternative to the two-stroke versions thanks to its user-friendly engine power delivery, which is welcomed by clubman riders and experts alike.

All the two-stroke versions have the following new features designed to give the machine a more technically polished feel. The engines, apart from the 125cc, feature a cylinder with new exhaust port geometry and new timing curves. Both of these developments improve low-rev engine control and stabilize the power delivery, providing exceptional standard-setting performance.
A new gear selector cam has been designed which was used in the earlier ‘Factory’ models and provides more positive shifting. Another ‘Factory’ model feature is the new CDI control unit now with even better performance and optimized mapping for the new cylinder.
The 300 4T four-stroke engine has also been upgraded. One of the most important new features is a new throttle with a redesigned internal ramp that gives better low-rev power control. Like the two-strokes, the four-stroke inherits the new CDI control unit with new dedicated mapping.
A series of new features on both the two-stroke and four-stroke models includes the following: New shock absorber port geometry, which is now higher and more progressive. New shock absorber piston with increased suspension sensitivity and progression. Together with the modified spark plug geometry the new piston generates decidedly more grip, making it more forgiving in the event of rider error. A new pump on the mechanical side of the front fork ensures more progressive impact absorption. New front fork oil, which improves stability at high temperatures maximizing smoothness. New chain tensioner affording a new adjustment range whilst making adjustments easier. The rear brake calliper has brake-pad anti-vibration systems which maximize precision and significantly reduce noise. New graphics and colours enhance the appearance.
