OVERVIEW

The Beta X-PRO approach to enduro has won over riders of all skill levels. For the 2027 model year, the X-PRO evolves to become even more capable, making it the ultimate adventure companion, no matter how you approach the trail.

The X-PRO sits perfectly in the sweet spot of Beta’s lineup. It serves as the bridge between the agile, entry-level Xtrainer and the race-equipped, high-spec RR Race models. The X-PRO is more robust and structured than the Xtrainer, yet remains simpler and more user-friendly than the full-blown race bikes.

Experienced riders love its versatility, seamlessly switching from fast tracks to technical Hard Enduro to singletrack thanks to an adaptable chassis and clicker settings that can be adjusted on the fly. Amateurs and weekend warriors appreciate the ease of use and confidence the bike delivers, keeping things comfortable even when the terrain gets demanding.

With chassis updates for 2027, the X-PRO reaches a new level of refinement. It caters to a wider range of riding styles with a precise, highly effective suspension adjustment system. The 2-stroke lineup benefits from fine-tuned power delivery and improved ride comfort, while the 4-stroke models debut a suite of advanced electronic rider aids.
