2020 Beta RR 50 Racing Technical Analysis & Specification Breakdown
Engineered by Beta for the enduro - offroad motorcycle segment, the 2020 Beta RR 50 Racing utilizes a 49.7 cc (3 cu in) liquid-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 40.3 x 39.0 mm (1.6 x 1.5 inches) with a 12.0:1 compression ratio.
Rider ergonomics and chassis geometry center around a 935 mm (36.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,415 mm (55.7 in) wheelbase engineered for quick, flickable steering geometry. The 6.5-liter (1.7 US gal) fuel tank paired with a rated consumption of 3.4 L/100 km provides an estimated theoretical range of roughly 191 km (119 miles) between fill-ups.
