Light, responsive, and built to be ridden hard, the Beta 125 RR Race 2-Stroke puts pure two-stroke performance into a race-focused enduro package. Its 124.8cc Beta-built two-stroke engine combines a Beta Progressive Valve power system with a Keihin PWK 36mm carburetor and a six-speed transmission, delivering the sharp throttle response and exciting powerband that makes a 125 so much fun to ride.
The Race edition takes things a step further with KYB 48mm closed-cartridge front suspension and a KYB rear shock, giving the 125 the suspension performance needed when the pace picks up and the terrain gets rough. The lightweight chassis, 21"/18" wheels, and competition-focused components make this bike incredibly agile and rewarding to ride.
And because this is a Race model, it's designed with performance in mind. The updated 2026 gearbox improves shifting feel and durability, while the race-spec chassis and suspension give riders the tools to push harder on the track or trail.
