info specifications
2021 BETA Evo 300 SS


Updated internal valving provides a more balanced feel while also providing more plushness over the small rollers. The shock valving has also been revised to work in conjunction with the new front fork settings.


The 300 SS "Super Smooth" model has added weight on the flywheel to increase inertia, that combined with other improvements, has resulted in an engine that is more manageable in medium-low revs

Hydro-Formed Frame and Tank

The EVO hydro-formed aluminum frame & tank is a work of art that is unmatched in beauty & performance.

Tubeless  Rear Tire

A Dunlop tubeless rear tire allows riders to run extremely low tire-pressure for maximum traction.

Dual Map Switch

A relocated dual map switch allows riders to choose between two power curves
