The 2021 Beta Evo lineup of observed trials motorcycles has five two-strokes and a lone four-stroke this year. 2021 isn’t a revolutionary year for Beta trials bikes, though there are some updates. The six Beta Evo motorcycles share the same basic chassis.
- The suspension has new internal valving. The goal is a plusher feel over small obstacles, along with an improvement in balance.
- All six 2021 Beta Evo trials bikes get new carburetor settings and mapping to match. In this case, the goal is a more linear throttle response that is more predictable. The two-strokes use a 28mm Keihin PWK carburetor for all displacements, with the four-stroke mill fed by a Mikuni CV carburetor.
- The 2021 Beta Evos get Bold New Graphics. Along with new stickers, the color of some of the plastics has changed. There’s more red and less black this year.
