2013 Harley-Davidson Road King Technical Analysis & Specification Breakdown
Positioned in Harley-Davidson's touring motorcycle lineup, the 2013 Harley-Davidson Road King utilizes a 1688 cc (103 cu in) v2, four-stroke layout. In factory specification, maximum torque reaches 135.6 Nm (100 lb-ft) at 3,250 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 98.4 x 111.3 mm (3.9 x 4.4 inches) with a 9.6:1 compression ratio.
On the scales, the Road King measures 367.9 kg (811 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 678 mm (26.7 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 5.6 L/100 km provides an estimated theoretical range of roughly 406 km (252 miles) between fill-ups.
