At the heart of the 2007 Beta REV 3 - 270 trial motorcycle, Beta pairs a 274.5 cc (16.8 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 76.0 x 60.5 mm (3.0 x 2.4 inches) with a 10.8:1 compression ratio.
On the scales, the REV 3 - 270 measures 72 kg (159 lbs) dry. Rider ergonomics and chassis geometry center around a 660 mm (26 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,310 mm (51.6 in) wheelbase engineered for quick, flickable steering geometry. The 3.2-liter (0.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
