Quick, precise, and lean—Beta’s 2025 RR Race models are built to do one thing: perform. With the name shortened to RR Race, Beta gets straight to the point with a lineup engineered to deliver race-level speed, control, and confidence.
Based on the new RR X-Pro platform, RR Race models receive focused upgrades to the engine, suspension, and chassis to create a bike that’s ready for everything from tight, technical tests to faster, wide-open courses—while maintaining the Rideability Beta is known for.
For 2025, Beta also targeted the 125 two-stroke with meaningful engine updates designed to boost performance across the entire rev range. A new piston and revised cylinder head increase power delivery and sharpen response, giving the 125 a stronger pull, a broader usable range, and a more aggressive top-end hit—without sacrificing low-end torque.
