MAIN FEATURES

SUSPENSION

SHC FRONT FORK

The SHC (Separate Hydraulic Chamber) front fork remains a cornerstone of the X-PRO chassis thanks to its asymmetrical design with separate function management – spring-loaded on the right fork leg and hydraulic on the left – which optimises performance and reduces weight by approximately 250 grams compared to a standard front fork.

For the 2027 model year, the suspension has been given a completely new setup, designed to further expand the bike’s range of use. Beta’s engineers focused on improving shock absorption, particularly in the initial phase of operation. The result is a new setting that is consistently precise and responsive, capable of maintaining optimal contact with the ground and increasing linearity of response. This evolution enhances riding comfort, catering to both the amateur seeking confidence and the pro rider tackling the toughest sections of Hard Enduro.

SUSPENSION

XPRO
Mono

In keeping with the character of the X-PRO, the monoshock has been specifically developed to work in perfect synergy with the SHC front forks, delivering optimal handling and consistently comfortable ride quality.

In MY27, the rear suspension has evolved thanks to the introduction of new aluminium components that help reduce the vehicle’s overall weight. From a hydraulic perspective, updates have focused on the brake to achieve greater separation between high- and low-speed flow, increasing absorption capacity and sensitivity to adjustments.

The real technical revolution lies in the external management system: this aspect is now adjusted via new adjustments that allow the rider to intervene directly on the track quickly and immediately, without requiring the use of any tools.

TORQUE AND LONG GEAR RATIOS

The RR X-PRO 4T 430 is designed for those seeking a high-performance engine, with substantial torque and a response that performs best when utilised with long gear ratios. It is the bike that transforms every acceleration into a constant thrust, without ever sacrificing stability and precision on the fastest sections.

INTEGRATED ELECTRONIC MANAGEMENT

The handlebar protection has been given a new look and features a redesigned control panel that brings together the bike’s controls. In addition to the traditional two engine maps (Standard and Soft) and the tried-and-tested two-level Traction Control, new features include 5-level Launch Control for lightning-fast starts and Quick Shift, for changing gears without releasing the throttle.

Trailtech instrumentation and details

The new Trailtech digital dashboard makes its debut: larger, more robust and easier to read, paired with a high-precision wheel sensor. The MY27 package adds new, softer anti-fatigue grips, a reinforced chain guide and an enlarged pinion guard.

MECHANICAL CHAIN TENSIONER

The 4-stroke engine features a new mechanical chain tensioner with a newly calibrated spring, replacing the previous hydraulic system. This modification optimises friction and operational smoothness, contributing to a more fluid engine response and more effective starts in both hot and cold conditions.

FRONT RECOVERY BELT

To emphasise the Extreme character of the RR X-PRO, a new front recovery belt has been introduced, customised with Beta embroidery, extremely useful for getting out of the most difficult situations.

COOLANT EXPANSION TANK

The coolant expansion tank, with a capacity of approximately 200cc, allows for the recovery of water that may be expelled from the radiator as temperatures rise, particularly during slower, more technical riding, or on extreme enduro sections.

ELECTRICAL SYSTEM AND BATTERY

The 4-stroke models benefit from an improved voltage regulator that ensures a higher, more stable and efficient voltage for all on-board components. This update increases the charging capacity of the lightweight lithium battery, ensuring maximum operational continuity of the bike even during the longest sessions.

SILENT BLOCKS

The silent blocks help reduce vibrations transmitted to the rider, making the ride more comfortable and less tiring.

FULL RED STYLE AND LED LIGHTING

The distinctive identity of the RR X-PRO 4T 430 is defined by its unmistakable full-red livery with contrasting black graphics. A sporty, modern and contemporary style, designed to complement the bike’s sleek lines and enhance freedom of movement in the saddle. Aesthetics meet functionality in the new headlight mask created by Beta’s designers, which refreshes the front-end look by housing a robust, latest-generation LED headlight. As well as delivering a significantly more powerful beam, it consumes less power, thereby extending the battery’s service life.
