Technical Overview
2005 Aprilia SR 50 Ditech Technical Analysis & Specification Breakdown
At the heart of the 2005 Aprilia SR 50 Ditech scooter motorcycle, Aprilia relies on a 49.4 cc (3 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 40.0 x 39.3 mm (1.6 x 1.5 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 1,340 mm (52.8 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.
