Engineered by Beta for the enduro - offroad motorcycle segment, the 2021 Beta RR 2T 50 features a 49.7 cc (3 cu in) liquid-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 40.3 x 39.0 mm (1.6 x 1.5 inches) with a 12.1:1 compression ratio.
On the scales, the RR 2T 50 measures 85 kg (187 lbs) dry. Rider ergonomics and chassis geometry center around a 920 mm (36.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 6.5-liter (1.7 US gal) fuel tank paired with a rated consumption of 2.4 L/100 km provides an estimated theoretical range of roughly 271 km (168 miles) between fill-ups.
Within MotoLibrary's Beta archive, this model family spans 2 indexed model years from 2021 to 2024, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
