Technical Overview
2007 Beta Ark 50 AC Technical Analysis & Specification Breakdown
Built around Beta's scooter motorcycle platform, the 2007 Beta Ark 50 AC utilizes a 49 cc (3 cu in) air-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 12.0:1 compression ratio.
On the scales, the Ark 50 AC measures 84 kg (185 lbs) dry. Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,240 mm (48.8 in) wheelbase engineered for quick, flickable steering geometry. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
