The 2025 Beta 350 RR X-PRO debuts on Beta’s completely redesigned X-PRO platform, bringing the mid-displacement four-stroke enduro into the most advanced chassis Beta has ever produced. The updated frame geometry, revised suspension mounting, modernized ergonomics, and ZF Sachs suspension components create a fundamentally new 350cc enduro experience. The 349cc liquid-cooled DOHC four-valve single with electronic fuel injection and six-speed gearbox delivers the balanced, versatile powerband through an entirely new chassis structure. Every torque specification applies to the new X-PRO platform — familiar engine, completely new context.
