Positioned in Beta's trial motorcycle lineup, the 2004 Beta Minitrial relies on a 49 cc (3 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 40.0 x 39.7 mm (1.6 x 1.6 inches) with a 13.3:1 compression ratio.
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.
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.
