Specifications
New electronic controls: For the first time in Beta’s 4-stroke range, two technologies borrowed from the world of racing – Launch Control (LC) and Quick Shift (QS) – are making their debut. Launch Control, adjustable across 5 levels, allows the X-PRO 4T MY27 to burst off at the start, managing torque delivery to maximise traction from the very first metre, eliminating time lost due to stalling or uncontrolled wheelies; a useful feature for the occasional trip to the motocross track. Quick Shift, on the other hand, allows you to engage gears without having to release the throttle, ensuring lightning-fast gear changes with no loss of power, covering more ground in less time. Two solutions that raise the technological level of Beta’s 4-stroke range to new standards, putting controls as refined as those on competition bikes in the rider’s hands, to deliver the best performance in all racing conditions. The control panel, which now houses the new LC and QS buttons, alongside the tried-and-tested two-level adjustable Traction Control (TC) and the map switch (with two engine maps), has consequently been redesigned, whilst retaining its position within the handlebar protection, which also sports a new look.
Voltage regulator: With the MY27, the RR X-PRO 4T models benefit from an improved voltage regulator, which guarantees a higher, as well as stable and efficient, voltage to the battery. This update has a positive impact on the entire wiring harness, ensuring a more constant and reliable power supply for all on-board electronic components. In addition, the battery’s charging capacity has been increased, benefiting the bike’s operational continuity even during the longest and most demanding sessions.
Titanium valves: The update to the new 4-stroke enduro models also includes titanium valves with a revised finish, a solution that further raises the standards of durability and reliability, confirming the constant focus on the development of key engine components.
New cam chain tensioner: The chain tensioner now adopts a purely mechanical solution (rather than a hybrid mechanical-hydraulic system with forced oil passages) with a spring of new calibration. These modifications optimise friction and operational smoothness, contributing to smoother running and more effective starts with both a warm and cold engine.
Grips: The new X-PROs feature new grips made from a softer compound, designed to reduce rider fatigue during longer, more demanding sessions. The more comfortable material effectively absorbs vibration transmitted from the handlebars, easing the strain on the forearms and allowing for a secure and comfortable grip even on the roughest terrain. The result is a greater connection with the bike and prolonged physical endurance — two factors that, in enduro, often make the difference between a good day in the seat and a bad one.
Speedometer: The X-Pro MY27 models are equipped with a new instrument (Trailtech), comparable to the previous one in terms of the information provided to the rider, but larger and easier to read, as well as more robust, to cope with even the most demanding use. This has been combined with a new pick-up sensor for wheel speed reading, which is precise and reliable.
LED headlight and headlight mask: Design and functionality come together in the new headlight mask created by Beta’s designers, which refreshes the bike’s look by integrating a robust, latest-generation LED headlight. In addition to delivering a more powerful beam, this results in lower power consumption, thereby extending the battery’s service life.
Front sprocket guard: The new guard has been redesigned to offer wider coverage and greater strength than the previous model, ensuring superior protection against impacts, debris and external elements during use, as well as greater safety for the rider (in compliance with even the most stringent competition regulations).
Suspension: The newly designed suspension on the RR X-PRO, featuring a short wheelbase and reduced travel, has been further refined through adjustments to the settings and the use of new aluminium components, which help to reduce the vehicle’s overall weight. The overall height of the bike remains at 930 mm (20 mm lower than the RR Race), allowing the rider to maintain better contact with the ground in every situation, from amateur outings to track riding, as well as in the most extreme conditions.
SHC (Separate Hydraulic Chamber) front fork: The asymmetrical front fork layout is retained, introduced to optimise hydraulic performance and reduce overall weight (by approximately 250g compared to a standard front fork). The division of roles between the right and left legs allows for greater control over all settings, with the right leg managing the spring action, whilst the left leg handles the hydraulics. What’s new? The MY27 tuning applied to the front fork aims to achieve the ideal balance between handling stability and riding comfort. The aim was to broaden the front fork’s range of use, focusing on improving absorption, particularly in the initial part of the travel (rather than at the end of travel). The result is a new setting that remains precise and responsive, capable of maintaining ideal contact with the ground whilst delivering a high level of riding comfort.
Rear Shock: Specifically developed to work in synergy with the X-Pro model’s SHC front fork, the rear shock has also received some updates. Specifically, changes have been made to the hydraulic damper to achieve greater separation between high- and low-speed operation. This aspect is now adjusted via a new external adjustment system, which requires no tools whatsoever. The different flow paths designed within the shock are intended to broaden the component’s range of use, increasing both comfort and damping capacity, improving sensitivity to different settings, and specifically separating the ability to adjust high- and low-speed damping in shock absorption.
In keeping with the X-PRO’s character, the suspension system has been designed to deliver optimum handling, with the bike’s overall ride quality remaining comfortable at all times and tailored to suit both amateur riders and professional Hard Enduro competitors. With the 2027 model year, the scope for customising the settings has been further improved, with the aim of broadening the vehicle’s range of use.
Frame: The adoption of the frame with an enlarged section in the main beam (+1 cm), which first appeared on the X-PRO MY25 models, is confirmed. This ensures a bike that is overall very precise and stable both when entering and navigating corners, capable of conveying a strong sense of confidence in managing the engine’s performance, from Hard Enduro to track riding.
Handlebar risers with silent blocks: Improved riding comfort also, and above all, depends on the grip on the handlebars, the main point of contact with the bike. The use of silent blocks for the handlebar mounts helps to reduce vibrations transmitted to the rider, making the ride more comfortable and less tiring.
Front lift strap: To emphasise the Extreme character of the RR X-PRO, the new front lift strap, customised with the Beta logo, has been retained; it is extremely useful for getting out of the most difficult situations.
Nissin brake pump: The X-PRO MY27 models are equipped with a cross-derived front brake calliper—small, lightweight and high-performance—which ensures incisive braking performance at the limit, whilst maintaining the typical modularity of the systems chosen by Beta’s engineers.
Radiators: To prevent any loss of reliability even in the most extreme conditions, the cooling system must always be kept in perfect working order. For this reason, the use of the coolant expansion tank (200cc) inside the frame has been retained, alongside the robust radiators introduced with the previous model year, which prevent deformation and consequent reductions in coolant flow.
Adjustable exhaust valve: Like all Beta 2-stroke Enduros, the X-Pro retains the adjustable exhaust valve, allowing precise external calibration of engine power delivery to suit the rider’s preferences.
Diaphragm clutch: Another trademark feature, also confirmed for the 2027 model year, is the use of a diaphragm-spring clutch, adjustable to three engagement levels via a simple mechanical operation.
