At the heart of the 2010 Harley-Davidson XL 1200C Sportster 1200 Custom custom - cruiser motorcycle, Harley-Davidson relies on a 1202 cc (73.4 cu in) air-cooled v2, four-stroke powerplant. In factory specification, maximum torque reaches 98 Nm (72.3 lb-ft) at 3,200 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 88.9 x 96.8 mm (3.5 x 3.8 inches) with a 9.7:1 compression ratio.
On the scales, the XL 1200C Sportster 1200 Custom measures 255 kg (562 lbs) dry. Rider ergonomics and chassis geometry center around a 710 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,520 mm (59.8 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
