At the heart of the 2005 Aprilia Leonardo 125 scooter motorcycle, Aprilia pairs a 124.9 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 56.4 x 50.0 mm (2.2 x 2.0 inches) with a 12.5:1 compression ratio.
Rider ergonomics and chassis geometry center around a 678 mm (26.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 770 mm (30.3 in) wheelbase engineered for quick, flickable steering geometry. The 9.3-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
