The EVO Factory models represent the racing EVOlution of Beta’s trial bikes and, as usual, are being launched on the market just before the start of the racing season, ready to compete at the highest levels.
The World Championship with George Hemingway (TR3 125), alongside the excellent placings of Matteo Grattarola (TRIALGP) and Andrea Sofia Rabino (GP WOMEN), as well as the respective victories in national championships, reaffirm the excellent rideability and performance introduced by the model.
The Model Year 2025 bike receives a major upgrade to the suspension, with the introduction of a new, larger diameter fork which provides major benefits both in use and in the ability to customise the settings.
The highlights of the new Factory MY 25 models, in terms of the ENGINE and FRAME AND SUSPENSION, are as follows:
ENGINE
2-Stroke
The differences between the engines equipping Factory versions and standard versions are as follows:
Magnesium crankcase with black finish: featuring a particularly eye-catching design, this component provides a weight reduction of 1,350 g, maximising the agility of the bike.
Trimmed clutch discs: created specifically to maximise clutch precision and controllability in every possible situation and particularly to make the most extreme repetitive actions easier to manage even at high rpm, such as big obstacles and rear wheel hops, ensuring extreme precision every time.
Black anodised engine oil plugs.
Titanium exhaust: on the 250/300 models this provides a weight reduction of over 600 g, as well as ensuring greater performance at medium-high engine speeds thanks to its greater internal diameter.
The EVO Factory 125’s exhaust, once again made of titanium, stands out from that of the larger engine sizes due to its internal structure, with an initial conical section (cylinder side) providing an increase in torque and acceleration at low rpms.
As is well known, the EVO Factory models are equipped with higher performance engines than the EVO models, and this characteristic is confirmed once again for MY 25.
Thanks to the reduced crankcase weight, the titanium header and reduced alternating masses, the bike is more manageable, while the engines guarantee improved performance and driveability, reaching another level of power and responsiveness.
The handling is, as always, at the top of their class, and vibration is minimised.
