Positioned in Aprilia's scooter motorcycle lineup, the 2005 Aprilia Scarabeo 50 Four Stroke relies on a 49.4 cc (3 cu in) air-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 41.0 x 37.4 mm (1.6 x 1.5 inches) with a 10.5:1 compression ratio.
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 1,250 mm (49.2 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
Within MotoLibrary's Aprilia archive, this model family spans 2 indexed model years from 2005 to 2009, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
