2007 Beta Alp 4.0 Technical Analysis & Specification Breakdown
Built around Beta's enduro - offroad motorcycle platform, the 2007 Beta Alp 4.0 relies on a 349 cc (21.3 cu in) single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 79.0 x 71.2 mm (3.1 x 2.8 inches) with a 9.5:1 compression ratio.
On the scales, the Alp 4.0 measures 133 kg (293 lbs) dry.
