Engineered by Harley-Davidson for the touring motorcycle segment, the 2008 Harley-Davidson FLHR Road King Firefighter utilizes a 1573.3 cc (96 cu in) air-cooled v2, four-stroke layout. In factory specification, maximum torque reaches 126.1 Nm (93 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain 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 FLHR Road King Firefighter measures 352.4 kg (777 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 759 mm (29.9 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 supports practical everyday commuting and weekend road stints.
