Technical Overview

1982 Suzuki GS 125 ESZ Technical Analysis & Specification Breakdown

At the heart of the 1982 Suzuki GS 125 ESZ naked motorcycle, Suzuki pairs a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 13.5 HP (9.9 kW) at 8,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 108 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

The 11.6-liter (3.1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 115 km/h (71 mph).
