At the heart of the 2007 Gilera Runner PureJet 50 scooter motorcycle, Gilera utilizes a 49.4 cc (3 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 40.0 x 39.3 mm (1.6 x 1.5 inches) with a 10.5:1 compression ratio.
On the scales, the Runner PureJet 50 measures 106 kg (234 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 9.7-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
