2018 Beta Evo 300SS REVIEW BY TOTAL MOTORCYCLE

Ever-increasing Technical Refinement

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 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 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.

2018 Beta Evo 300SS Totalmotorcycle.com Key Features

Evo 2 Stroke:

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 bare anodized aluminum frame and black wheels with white/red decals.
