1990 Suzuki DR 350 S Technical Analysis & Specification Breakdown
Built around Suzuki's enduro - offroad motorcycle platform, the 1990 Suzuki DR 350 S relies on a 349 cc (21.3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 27 HP (19.7 kW) at 7,600 rpm while maximum torque reaches 29 Nm (21.4 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 77.4 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the DR 350 S measures 141 kg (311 lbs) wet (curb), translating to a power-to-weight ratio of 0.19 HP/kg (5.22 kg per horsepower). Rider ergonomics and chassis geometry center around a 899 mm (35.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control. The 9-liter (2.4 US gal) fuel tank paired with a rated consumption of 5.5 L/100 km provides an estimated theoretical range of roughly 164 km (102 miles) between fill-ups, while factory top speed is listed at 126 km/h (78 mph).
