MY26 RR390 X-PRO 4T EFI

Description

MY2026 Beta RR 390 X-PRO 

With an ideal handling to power ratio, the winning feature of the MY26 RR 390 X-PRO lies in its outstanding traction and big bore torque feel.

Introduced last year as a repositioned model in Beta’s lineup, the RR X-PRO received a popular response amongst riders of all levels. For MY26, the RR X-PRO range is back, with new looks and further refinements.

Expert riders were quick to embrace the X-PRO’s versatility—its uniquely adaptable frame and easily adjustable suspension make it just as capable on high-speed tracks as it is on demanding Hard Enduro trails. Meanwhile, amateur riders found confidence in its user-friendly design and balanced performance, which delivers both control and comfort, even in the most challenging terrain.

RR X-PRO Features

Frame Returning from the MY25 X-PRO models, the reinforced frame featuring a larger main spar section (vs MY2024) makes a comeback in the MY26 lineup. This design maintains balanced weight distribution while improving overall stability. The increased rigidity delivers just the right amount of flex, offering precise cornering performance whether navigating tight single tracks or tackling demanding Hard Enduro terrain.

Suspension First introduced in the MY2025 RR X-PRO models, the revised ZF suspension system continues to deliver an ideal blend of control and comfort. With a seat height of 930 mm (20 mm lower than the RR Race models) riders enjoy a more planted and confidence-inspiring ride, no matter the conditions.

SHC Fork (Single Hydraulic Chamber) The SHC fork was developed to optimise hydraulic efficiency and reduce weight—shaving approximately 250g. The fork’s dual-leg system separates the forks function: the right leg handles spring action, while the left leg controls hydraulic damping. Both stanchions have been refined, with a completely redesigned spring guide to enhance oil flow, reduce high-speed pressure spikes, and improve internal lubrication. The result is a more linear, predictable fork response that adapts quickly and smoothly to varied terrain, providing a notably freer and moreresponsive ride than traditional systems.

Swingarm For MY26, the rear axle diameter has been increased by 2 mm, now measuring 22 mm. This upgrade enhances stiffness and torsional resistance, significantly improving rear-endperformance during aggressive riding and high-load situations.

Handlebar Map Switch Retained from last year’s model, the handlebar-mounted map switch remains integrated within the handlebar pad, similar to Beta’s MX lineup. This intuitive placement makes it easy to adjustengine mapping on the fly for optimal performance in changing conditions.

Nissin Front Brake System As seen on the RX 450, the RR X-PRO MY26 features a new Nissin front brake caliper. More compact, lighter, and more efficient than the previous version, it delivers improved braking modulation and a more responsive feel for greater rider confidence.

Radiators and Cooling System Reliability is critical, especially under extreme riding conditions. That’s why the MY26 models retain the integrated coolant expansion tank within the frame and introduce newly reinforced radiators. These updated components are designed to resist deformation, maintaining optimal coolant flow and ensuring consistent engine temperatures even under heavy stress.

Graphics Bold, aggressive, and unmistakably modern—the MY26 RR X-PRO range debuts a striking new all-red livery, accented with sharp black graphics. The fresh look reflects the bike’s contemporaryedge and racing DNA.

LED Tail Light Further elevating its design, the MY26 receives a new LED tail light. More robust and stylish than the previous version.

Traction Control: The 4T range features traction control, helping riders get through the toughest of conditions. The switch is now mounted on the handlebar pad.
