Positioned in Suzuki's naked motorcycle lineup, the 2010 Suzuki Gladius 400 utilizes a 399 cc (24.4 cu in) oil & air-cooled v2, four-stroke layout. Internal engine geometry specifies a bore and stroke of 56.5 x 49.5 mm (2.2 x 1.9 inches) with a 11.5:1 compression ratio.
On the scales, the Gladius 400 measures 199 kg (439 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,445 mm (56.9 in) wheelbase engineered for balanced agility and highway composure. The 14.5-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
