A 431cc four-stroke enduro with strong, usable power. Aimed at experienced trail riders and enduro racers.
New frame (Dirt Bike 2025). The claimed '2027 RR Race 4T race-type engine cases' is a Race-model change and happened in 2025, not 2027 (Dirt Bike 2025 off-road guide).
All-new frame; engine revised with a repositioned crankshaft and twin injectors; traction control added 2023. Continues as the RR Race after 2024; 2027 RR Race 4T moves to race-type engine cases (electric start only).
Displacements reset to 350/390/430/480; fuel injection on the 350 from 2015 and the rest from 2016; push-button start across the range from 2017.
First in-house DOHC four-stroke, carbureted, six-speed; a 2012-only cross-country version was offered.
Beta chromoly chassis powered by a KTM-sourced RFS four-stroke engine.
Beta's MY27 page gives dry weight as both 107.5 and 108.5 kg.
