Positioned in Aprilia's super motard motorcycle lineup, the 2021 Aprilia SX 50 Factory relies on a 50 cc (3.1 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 11.5:1 compression ratio.
On the scales, the SX 50 Factory measures 104 kg (229 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 875 mm (34.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,395 mm (54.9 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank paired with a rated consumption of 3.14 L/100 km provides an estimated theoretical range of roughly 223 km (139 miles) between fill-ups.
