2018 Beta Xtrainer Dirt Bike Torque Specs
Shop parts for a 2018 Beta Xtrainer Dirt Bike.
The 2018 Beta Xtrainer continues the trail-focused 300cc two-stroke with suspension refinements and improved ergonomics. The power valve-equipped liquid-cooled single delivers its approachable power band through a chassis now well-validated for trail use across varied rider weights and abilities. Refined suspension damping settings improve feedback for newer riders learning to read trail terrain — the Xtrainer’s primary audience. Axle nut torque at 70 Nm (rear) and 40 Nm (front) reflects the lighter loads this trail-specific machine generates compared to competition enduro models.
