Built around Suzuki's enduro - offroad motorcycle platform, the 2012 Suzuki DR-Z400S features a 398 cc (24.3 cu in) oil & air-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 90.0 x 62.6 mm (3.5 x 2.5 inches) with a 11.3:1 compression ratio.
On the scales, the DR-Z400S measures 144 kg (317 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 935 mm (36.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,485 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 10-liter (2.6 US gal) fuel tank paired with a rated consumption of 3.62 L/100 km provides an estimated theoretical range of roughly 276 km (171 miles) between fill-ups.
