2006 Beta Alp 125 Technical Analysis & Specification Breakdown
Engineered by Beta for the trial motorcycle segment, the 2006 Beta Alp 125 utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 54.0 x 54.0 mm (2.1 x 2.1 inches) with a 10.0:1 compression ratio.
On the scales, the Alp 125 measures 101 kg (223 lbs) dry. Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 6.8-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
