Built around Suzuki's motorcycle platform, the 2025 Suzuki Drz4Sm pairs a 398 cc engine architecture with road-focused gearing. In factory specification, maximum torque reaches 37 Nm, transferring power to the rear wheel through a 5-speed constant mesh gearbox. Internal engine geometry specifies a bore and stroke of 90.0 mm x 62.6 mm (3.5 in. x 2.5 in.) with a 11.1:1 compression ratio.
On the scales, the Drz4Sm measures 154 kg (340 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 mm (0 in) wheelbase engineered for quick, flickable steering geometry. The 8.7-liter (2.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
