At the heart of the 2010 Polini 911 GP6 minibike, sport motorcycle, Polini pairs a 39.7 cc (2.4 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 4.2 HP (3.1 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 36.0 x 39.2 mm (1.4 x 1.5 inches).
On the scales, the 911 GP6 measures 20 kg (44 lbs) dry. Rider ergonomics and chassis geometry center around a 460 mm (18.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 1.5-liter (0.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
