At the heart of the 2016 Suzuki AX4 naked motorcycle, Suzuki features a 149.5 cc (9.1 cu in) air-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 57.0 x 58.6 mm (2.2 x 2.3 inches) with a 9.5:1 compression ratio.
On the scales, the AX4 measures 133 kg (293 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 765 mm (30.1 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 12.5-liter (3.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
