Positioned in Harley-Davidson's touring motorcycle lineup, the 2008 Harley-Davidson FLHRC Road King Classic utilizes a 1573.3 cc (96 cu in) air-cooled v2, four-stroke layout. In factory specification, maximum torque reaches 125.6 Nm (92.6 lb-ft) at 3,500 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).
On the scales, the FLHRC Road King Classic measures 351.5 kg (775 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 749 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,613 mm (63.5 in) wheelbase engineered for planted straight-line stability. The 22.71-liter (6 US gal) fuel tank paired with a rated consumption of 4.35 L/100 km provides an estimated theoretical range of roughly 522 km (324 miles) between fill-ups.
