Brand new 2023 Beta EVO 250cc. In stock @ John Lee and Sons Motorcycles. The UK’s bestselling trials bike, please see below for the welcome changes to the new 2023 model.
EVO 250 2T – This is the ideal bike for riders looking for an agile and easily controllable 2-stroke, with a more docile temperament and with slightly less power and torque than the range-topping model. The Evo 250 is ideal for the amateur looking for class-beating performance combined with precisely manageable power and impeccable rideability.
Tank cover: with a new design. The shape better envelops the frame and allows all the cable routing to be covered, for a clean and more orderly look. And this new form also effectively incorporates the mapping switch. 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.
Graphics: the bike’s look and performance are accentuated in equal measure with the latest EVO update. The geometric graphics and new anodised aluminium swingarm ensure an elegantly natural look reminiscent of the racing world. The frame is painted in distinctive Beta red to accentuate the beauty of the hydro-formed aluminium structure, a hallmark feature of the EVO. The filter box is now black again but remains the same functionally- speaking, as does the dedicated TwinAir foam filter. The fork sheaths are now in characteristic Beta red.
New shock calibration: the EVO shocks come complete with all the adjustments a rider needs to tailor the bike and identify the ideal set-up but, in order to enhance the rideability, the Betamotor technicians have harnessed their experience to implement a series of setting updates to boost the progressiveness, responsiveness and damping. As for the fork, the settings and quantity of oil contained in the two stanchions have been revised in order to boost the progressive response during the most extreme drops. This means that EVO is equipped with an asymmetric fork, with the left- and right-hand stanchions differing both functionally and in internal volume. The left-hand side features adjustable spring length, for setting ride height, while the hydraulic functions of the fork are settable on the right- hand stanchion, for customising the damping behaviour and responsiveness of the front end. By using different oil volumes calibrated specifically for the left- and right-hand stanchions, both the progressiveness of the fork and the precision with which feel is transmitted to the rider have been improved. As for the shock, and in order to improve the bike’s readiness, Beta has worked on the setting, boosting reactivity during the rebound phase. This allows EVO to offer the rider a greater sense of lightness, particularly when ‘bouncing’ to reposition between obstacles.
The larger volume Beta 2T engines have undergone significant updates, all implemented in order to improve vehicle performance and rideability, in line with the Beta philosophy. The new components equipping the EVO 2023 include:
Crankshaft and piston rod, the latter with an interaxle spacing that is reduced by 1.5 mm for a length of 114.5 mm. These new components offer multiple benefits, both on the performance side, for more rounded delivery, and in terms of the vehicle’s dynamics. The bike is more manageable thanks to a reduction in its weight and alternating masses. Handling is improved while vibration is reduced.
Cylinder: brand new. For this component, the timing has been revised to improve the torque at low engine speeds, while the overall weight is reduced.
Cylinder head: The new combustion chamber improves delivery at low speeds, making it more progressive and tractable, while retaining the same engine performance a
