At the heart of the 2003 Suzuki GZ 250 custom - cruiser motorcycle, Suzuki relies on a 249 cc (15.2 cu in) single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 72.0 x 61.2 mm (2.8 x 2.4 inches) with a 9.0:1 compression ratio.
On the scales, the GZ 250 measures 137 kg (302 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 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
