RR 350 X-Pro 4-Stroke
RIDE LIKE AN X-PRO
OVERVIEW
The Beta X-PRO approach to enduro has won over riders of all skill levels. For the 2027 model year, the X-PRO evolves to become even more capable, making it the ultimate adventure companion, no matter how you approach the trail.
The X-PRO sits perfectly in the sweet spot of Beta’s lineup. It serves as the bridge between the agile, entry-level Xtrainer and the race-equipped, high-spec RR Race models. The X-PRO is more robust and structured than the Xtrainer, yet remains simpler and more user-friendly than the full-blown race bikes.
Experienced riders love its versatility, seamlessly switching from fast tracks to technical Hard Enduro to singletrack thanks to an adaptable chassis and clicker settings that can be adjusted on the fly. Amateurs and weekend warriors appreciate the ease of use and confidence the bike delivers, keeping things comfortable even when the terrain gets demanding.
With chassis updates for 2027, the X-PRO reaches a new level of refinement. It caters to a wider range of riding styles with a precise, highly effective suspension adjustment system. The 2-stroke lineup benefits from fine-tuned power delivery and improved ride comfort, while the 4-stroke models debut a suite of advanced electronic rider aids.
Features
LOWER SEAT HEIGHT
The X-PRO maintains a 36.6 inches seat height, which sits almost an inch lower than the RR Race models. This gives riders a much easier reach to the ground during technical hard enduro sections or amateur trail rides.
NISSIN BRAKING SYSTEM
Equipped with a compact, lightweight, motocross-derived Nissin front brake setup that offers immense stopping power with excellent lever modulation.
ROBUST FRAME
Confirms the use of the upgraded frame layout (featuring a 10mm wider main spar) introduced on previous models, offering superb stability and cornering precision.
SOFTER COMPOUND GRIPS
New, softer grips reduce rider fatigue and arm pump by absorbing trail vibration, allowing you to stay on the gas longer.
LED HEADLIGHT & MASK
A redesigned, aggressive front mask houses a latest-generation LED headlight. It throws a much brighter, safer beam while drawing less power from the battery.
DIAPHRAGM CLUTCH
The classic cup-spring clutch returns, offering three mechanical adjustment levels to customize lever pull and engagement feel.
TOOLLESS REAR SHOCK ADJUSTMENT
The rear shock, tuned to balance the SHC fork, features a redesigned hydraulic damper that better separates high-speed and low-speed dampening circuits. Best of all, adjustments can now be made externally by hand without needing any tools
HEAVY DUTY CHAIN GUIDE
Features a reinforced structure to withstand mud, rocks, and hard impacts from ruts and logs. A straighter, stronger guide ensures final drive stability, prevents thrown chains, and protects the swingarm.
COOLING SYSTEM W/ RECOVERY TANK
Features heavy-duty radiators that resist deformation and coolant flow reduction, paired with a 200cc coolant expansion tank integrated directly inside the frame spar to prevent boil-overs.
FLEXFIX HANDLEBAR MOUNTS
Handlebar risers utilize silent-block rubber mounts to isolate the rider's hands from engine vibration.
FRONT RECOVERY STRAP
Includes the factory-installed front recovery strap featuring the Beta logo, an indispensable tool for tugging the bike out of nasty mud holes or up vertical rock faces.
