Overview

Description

Ever-increasing technical refinement



The new Evo My 2018 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 now provide outstanding levels of technical refinement, performance and reliability.



As always, the hallmark of the Beta family is sharp-edged efficiency for both pros – from regional championships through to world championships – and less expert amateur riders.



The 2-stroke range offers four different engine sizes: 125, 250, 300 and 300 SS – where “SS” stands for Super Smooth, a trials bike with a softer engine power delivery than its more aggressive counterparts, designed for off-road lovers who just want to focus on having fun.



The 4-stroke version, instead, has a 300 cc power unit and offers a sound and power delivery alternative to the 2-stroke models thanks to user-friendly engine design.



Evo 2T



All the 2-stroke versions – including the 300 SS – have the following new features, designed to give the bikes a more technically polished feel.



Engines boast new low-friction main bearings that reduce energy loss and thus improve low-rev performance. A look at the suspension shows 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.



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.
