1982 Suzuki DR 125 S Technical Analysis & Specification Breakdown
Engineered by Suzuki for the enduro - offroad motorcycle segment, the 1982 Suzuki DR 125 S features a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 10 HP (7.3 kW) at 9,500 rpm while maximum torque reaches 9.5 Nm (7 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 80.6 HP per liter and a 2,000 rpm working window between peak torque (7,500 rpm) and peak power (9,500 rpm), 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 125 S measures 112 kg (247 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.2 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,340 mm (52.8 in) wheelbase engineered for quick, flickable steering geometry. The 8.5-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 95 km/h (59 mph).
