At the heart of the 2008 Beta REV 80 trial motorcycle, Beta relies on a 79.6 cc (4.9 cu in) single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 48.0 x 44.0 mm (1.9 x 1.7 inches) with a 14.7:1 compression ratio.
On the scales, the REV 80 measures 64 kg (141 lbs) dry. Rider ergonomics and chassis geometry center around a 652 mm (25.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,230 mm (48.4 in) wheelbase engineered for quick, flickable steering geometry. The 2.5-liter (0.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
