Positioned in Gilera's enduro - offroad motorcycle lineup, the 2002 Gilera GSM 50 utilizes a 49.9 cc (3 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 13.9 HP (10.1 kW) at 8,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive.
On the scales, the GSM 50 measures 103 kg (227 lbs) wet (curb), translating to a power-to-weight ratio of 0.13 HP/kg (7.41 kg per horsepower). Rider ergonomics and chassis geometry center around a 845 mm (33.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 115 km/h (71 mph).
