Built around Polini's minibike, sport motorcycle platform, the 2008 Polini 911 GP5 features a 39.9 cc (2.4 cu in) single cylinder, two-stroke configuration. 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 GP5 measures 22 kg (49 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.
