Built around Beta's trial motorcycle platform, the 2008 Beta REV-4T features a 249.6 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 77.0 x 53.6 mm (3.0 x 2.1 inches) with a 11.5:1 compression ratio.
On the scales, the REV-4T measures 75 kg (165 lbs) dry. Rider ergonomics and chassis geometry center around a 680 mm (26.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,319 mm (51.9 in) wheelbase engineered for quick, flickable steering geometry. The 2.2-liter (0.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
