At the heart of the 2010 Harley-Davidson XL 1200X Sportster Forty-Eight custom - cruiser motorcycle, Harley-Davidson utilizes a 1200 cc (73.2 cu in) air-cooled v2, four-stroke layout. In factory specification, maximum torque reaches 107 Nm (78.9 lb-ft) at 4,000 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 1200X Sportster Forty-Eight measures 257 kg (567 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 680 mm (26.8 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 8-liter (2.1 US gal) fuel tank paired with a rated consumption of 5.6 L/100 km provides an estimated theoretical range of roughly 143 km (89 miles) between fill-ups.
