Agile. Responsive. Versatile. Built to conquer the trail.
The 2027 Beta RR 350 X-Pro 4T delivers an exciting combination of lightweight handling and usable four-stroke power. Its 349.1cc liquid-cooled single-cylinder engine is designed for a higher-revving riding style while maintaining smooth, linear power delivery, making it an excellent choice for riders who want the traction and engine braking of a 4-stroke without the heavier feel associated with larger-displacement machines.
The RR 350 X-Pro sits between Beta's approachable Xtrainer and competition-focused RR Race models, offering a versatile platform for everything from flowing singletrack and technical terrain to faster trail riding. For 2027, Beta adds new electronic rider aids and further chassis and suspension refinements.
