Radiator Shrouds
The new shrouds are narrower than before to give the rider more freedom of movement, especially when cornering. Designed to be sleed and also contribute to the revised, simple, and essential new look of the bike.
Engine Maps
Advanced electronics take full advantage of the increased torque at low to medium engine speeds made available by the new exhaust header. Four stroke models now feature dedicated new engine management maps that spread the power curve out more uniformly across the entire usable range of the engine.
Rear Linkage
Unlinke others in the category, Beta RR models have a linkage system in the rear suspension for a more plush trail ride feel with the ability to react to sharp square-edged hits as well.
