Engine maps
The new 4-stroke engine maps improve power delivery in terms of linearity and usability at all revs. Whatever the displacement, Beta engineers improved their linearity and usability, to better manage the power available, at any speed.
A distinctive design
The RR X-PRO 350 4T is highly distinctive: it features an all-red livery with contrasting black graphics, giving it a sporty and contemporary style. The new LED rear light, which is more compact and robust, completes the look and guarantees reliability even in the most challenging conditions. The design is not only aesthetic but also functional, enhancing performance.

SHC fork
Redesigned to offer superior performance, the new fork reduces weight by approximately 250 g and introduces separate function management: the right leg controls elasticity, while the left leg controls hydraulics.
FRONT RECOVERY STRAP
To emphasise the Extreme character of the RR X-PRO, a new front recovery strap has been introduced, customised with Beta embroidery, which is very useful for getting out of the most difficult situations.
Battery
All 4-stroke models are equipped with a new, lighter and more-performing battery to ensure reliable starting under any usage conditions.
COOLANT EXPANSION TANK
The coolant expansion tank, approximately 200cc, allows you to recover water that could be expelled from the radiator as temperatures rise, particularly when riding slowly and technically, or during extreme enduro passages.
HANDLEBAR MAP SWITCH
The map switch button located on the handlebar allows you to select two engine maps: Full Power, which offers all the power and responsiveness of the engine, and Soft, which softens the power delivery, making it more manageable on slippery surfaces or when greater traction is needed. The same button is also used to select the level of Traction Control intervention.
XPRO Mono
In keeping with the character of the X-PRO, the suspension system generates optimal vehicle handling, with the bike’s overall behaviour always comfortable and suitable for both amateur riders and pros who are dedicated to Hard Enduro.
NISSIN BRAKE PUMP
The new X-PRO My26 models are equipped with a new front brake caliper, coming from motocross, which is smaller, lighter and more efficient than the previous one, ensuring significantly more effective performance when braking at the limit, while maintaining the typical modularity of the systems chosen by Beta’s engineers.
Silent block
The Silent Block reduces vibrations transmitted to the rider, making the grip more comfortable and less tiring.
