Beta's biggest four-stroke enduro (478cc), with heavy torque but a manageable feel. Aimed at experienced riders and open-class 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.
Same 498cc engine as the 2010–2011 RR 520, renamed to its true displacement.
497.4cc, carbureted Keihin 39mm.
Beta's MY27 page gives dry weight as both 107.5 and 108.5 kg.
