At the heart of the 2012 Harley-Davidson FXDB Dyna StreetBob custom - cruiser motorcycle, Harley-Davidson features a 1573.3 cc (96 cu in) air-cooled v2, four-stroke configuration. In factory specification, maximum torque reaches 124.8 Nm (92 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 111.3 mm (3.8 x 4.4 inches) with a 9.2:1 compression ratio.
On the scales, the FXDB Dyna StreetBob measures 303.9 kg (670 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 648 mm (25.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,631 mm (64.2 in) wheelbase engineered for planted straight-line stability. The 17.79-liter (4.7 US gal) fuel tank paired with a rated consumption of 5.47 L/100 km provides an estimated theoretical range of roughly 325 km (202 miles) between fill-ups.
