2010 Beta Minicross R 12 Technical Analysis & Specification Breakdown
At the heart of the 2010 Beta Minicross R 12 minibike, cross motorcycle, Beta relies on a 49 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 39.5 x 40.0 mm (1.6 x 1.6 inches) with a 12.5:1 compression ratio.
On the scales, the Minicross R 12 measures 51 kg (112 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,100 mm (43.3 in) wheelbase engineered for quick, flickable steering geometry. The 2-liter (0.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
