The new 2018 Evo trials range, which builds and improves on the previous versions, is about to hit the market. Beta’s engineers have been hard at work on the fine details, resulting in bikes that further continue to provide outstanding levels of technical refinement, performance and reliability.

As always, the hallmark of the Beta family is known for their sharp-edged performance for pros as well as amateur riders.

The 4-stroke version is available in a 250cc or 300cc engine and offers a sound and power delivery alternative to the 2-stroke models thanks to user-friendly engine design.

Evo 4T

The 300 4T (four-stroke) engine has undergone further development, resulting in a new twin-spark control unit – this ensures improved combustion to boost performance and throttle response precision – and a spark plug with a new electrode, which now protrudes further into the combustion chamber. This gives more immediate, precise ignition, ensuring cleaner carburetion under all riding conditions.

A larger oil pump has also been introduced, reducing engine braking significantly and completely eliminating the on-off effect at low revs. Moreover, the internal exhaust layout has been revised, sharpening engine performance and linearity to ensure outstanding consistency across the entire bike handling range.

A look at the suspension shows – as on the 2T – that both rear shock and front fork have been calibrated to give greater progression, absorbing and dampening major impacts with even greater efficiency. Both front fork legs now use the same amount of oil to help simplify servicing.

The wheels feature hubs that have been reinforced in the disc and sprocket attachment areas to boost impact-resistant reliability and are now mounted with Dunlop tires.

The design has also been overhauled, with new graphics and colors on the anodized aluminum frame and black wheels with white/red decals.
