At the heart of the 2020 Beta RR 125 2T enduro - offroad motorcycle, Beta relies on a 124.8 cc (7.6 cu in) air-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 54.0 x 54.5 mm (2.1 x 2.1 inches) with a 15.0:1 compression ratio.
On the scales, the RR 125 2T measures 94 kg (207 lbs) dry. Rider ergonomics and chassis geometry center around a 930 mm (36.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,477 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
