Built around Polini's minibike, sport motorcycle platform, the 2005 Polini 911 GP 3 Race relies on a 39.9 cc (2.4 cu in) single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 36.0 x 39.0 mm (1.4 x 1.5 inches) with a 16.5:1 compression ratio.
On the scales, the 911 GP 3 Race measures 22 kg (49 lbs) dry. Rider ergonomics and chassis geometry center around a 425 mm (16.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops.
