Built around Beta's trial motorcycle platform, the 2008 Beta Minitrial 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 13.9:1 compression ratio.
On the scales, the Minitrial measures 42.5 kg (94 lbs) dry. Rider ergonomics and chassis geometry center around a 570 mm (22.4 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,020 mm (40.2 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.
Within MotoLibrary's Beta archive, this model family spans 5 indexed model years from 2004 to 2010, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
