Thanks to the innovations introduced with the previous Model Year, which make the EVO range stand out right at the top of the Trial sector, all recent additions to the bike are confirmed for 2024, with updates however to the aesthetic impact, with new graphics which are released from the traditional Beta red.

The main new feature from the point of view of the equipment involves the introduction of the electronic key which plays a dual role, combining the more traditional passive bike and rider safety function traditionally represented by a Kill-Switch with an innovative anti-theft function.

The EVO range is one of the most extensive in this class, and continues to offer a total of six different models, each with its own character and able to meet the needs of all riders, raising the potential and level of enjoyment that each experience:

EVO 300 2STR

This is the ideal bike for riders looking for an agile and powerful 2-stroke, with range-topping power and torque. The Evo 300 is ideal for the experienced rider looking for class-beating performance combined with precisely manageable power and impeccable reliability.


This new electronic device holds an exclusive European patent awarded to Betamotor (EP3064405B1), and provides an anti-theft function as well as protecting the bike and its rider.
The electronic key is a two-part component: one part remains fastened to the bike’s handlebars, while the other is magnetic (worn by the rider with a cord around their wrist), activating a mechanism in the event they are disconnected.


The shape envelops the frame and allows all the cable routing to be covered, for a clean and more orderly look. The mapping switch is also located inside it. It is, indeed, worth remembering that the EVO offers a choice of two different engine maps that the rider can select with a convenient button on the tank cover. This location makes the button easy to reach while offering protection against knocks and unintentional operation, while an LED indicator lets the rider immediately identify which map is currently in use.


As well as optimising the air flow directed to the radiator, it also boasts a greater protective surface in the cap and radiator body area, to prevent these components from sustaining damage when in contact with branches, stones or in the case of a fall.

The innovations introduced to the largest displacement two-stroke models (250/300) also include:

  • Crankshaft and piston rod with reduced interaxle spacing for more rounded delivery and improved vehicle dynamics.
  • Cylinder and head: overhauled timing and combustion chamber, providing improved torque at low rpms, while retaining engine performance at higher speeds.
  • Engine map: optimised in order to set up the components in the best possible way and exploit the engine’s power and docility.
  • Exhaust manifold: a manifold protection has been installed to avoid any overheating and to protect the manifold from impacts. As well as being functional, this rounds out the bike’s overall look (also on 125 two-stroke).
