Engineered by Suzuki for the super motard motorcycle segment, the 2019 Suzuki DR-Z400SM features a 398 cc (24.3 cu in) liquid-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-Z400SM measures 146 kg (322 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 890 mm (35 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,460 mm (57.5 in) wheelbase engineered for balanced agility and highway composure. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
