Built around Gilera's scooter motorcycle platform, the 2011 Gilera Stalker 50 utilizes a 49.3 cc (3 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 5.8 HP (4.2 kW) at 6,500 rpm while maximum torque reaches 4.8 Nm (3.5 lb-ft) at 6,250 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 40.0 x 39.3 mm (1.6 x 1.5 inches).
Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,240 mm (48.8 in) wheelbase engineered for quick, flickable steering geometry. The 5.6-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
