EVO 300 4T MY 2024

EVOlution Trial

The EVO Factory models represent the racing EVOlution of Beta's trial bikes and, as usual, are being launched on the market in February, just before the start of the racing season, ready to compete at the highest levels.

George Hemingway’s World Championship (TR3 125), alongside the excellent results of Matteo Grattarola (TRIALGP) and Andrea Sofia Rabino (GP WOMEN), and in addition to the respective victories in national championships, reaffirm the excellent driveability and performance provided by the Factory model.

For Model Year 2024, some updates have been made which increase the model's refinement, while maintaining its racing pedigree.

The highlights of the new Factory MY 24 models, in terms of the ENGINE and FRAME AND SUSPENSION, are as follows:


The differences between the engines equipping Factory versions and standard versions are as follows:


The 4-stroke Factory variant also benefits from a series of upgrades relative to the standard EVO version. The electronic control unit receives a higher power rating, which translates to improved spark stability and improved combustion at all engine speeds. In order to provide an outlet for the greater available power, the EVO Factory 4-stroke is also equipped with a lighter weight and higher performance titanium silencer.


In terms of the frame and design, the new Evo Factory My 2024 differs from the standard version as follows:

  • Gold Front Forks: the Evo Factory 24 is confirmed to have gold forks, which provide the model with both aesthetic and functional benefits. The colour is indeed the result of a TIN treatment, allowing for smoother sliding of the fork, whose hydraulic management remains entrusted to the recently introduced internal damping system. The continuous refinement of the settings ensures a suspension package which is at the top of the range in the trial bike sector, thanks in no small part to its combination with the mono-shock that has an optimised spring guide geometry (with red spring).
  • Progressive linkage: the configuration of the rear suspension linkage is more progressive, in order to ensure greater traction and provide superior feel to the rider. This facilitates wheelies and helps overcome large obstacles.
  • New steering yokes machined from billets with blue anodised finish: providing stiffness and lightness (weighing around 100 g less than std models), they also feature fore-aft adjustable handlebar brackets to let the rider find their ideal position. The new colour introduced for MY 24 also lends the bike a zero-compromise appearance.
  • Chain adjusters, handlebar end plugs and footpegs with black anodised finish: the footpegs are durable, lightweight components, with the non-slip steel pins ensuring maximum grip.
  • Version-specific radiator hoses in red silicone: offering improved cooling performance, these components also give the bike a thoroughbred racing look.
  • Galfer racing brake discs: these discs offer maximum braking power and are extremely light weight, which contributes to reducing unsprung mass and maximises the bike's rideability.
  • BrakTec brake and clutch master cylinders.
  • Rear brake calliper with anti-vibration system for pads.
  • New blue anodised Morad wheels.
  • Michelin X-light tyres: leader in the sector in terms of weight, performance and grip in all situations.
  • New graphics: red and blue have always been the colours used for Beta's race-ready models, and this new EVO Factory does not disappoint. The Beta red of the plastic parts and decals is perfect paired with the details and elegant new components in Ergal blue. The model's look is further enhanced by the new matte-gloss graphics, with the matte red parts contrasting with the glossy blue and white.
