Positioned in Harley-Davidson's custom - cruiser motorcycle lineup, the 2011 Harley-Davidson FLSTSB Softail Cross Bones relies on a 1584 cc (96.7 cu in) air-cooled v2, four-stroke powerplant. In factory specification, maximum torque reaches 127 Nm (93.7 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 95.3 x 111.1 mm (3.8 x 4.4 inches) with a 9.2:1 compression ratio.
On the scales, the FLSTSB Softail Cross Bones measures 317.5 kg (700 lbs) dry. Rider ergonomics and chassis geometry center around a 765 mm (30.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,630 mm (64.2 in) wheelbase engineered for planted straight-line stability. The 19.7-liter (5.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
