At the heart of the 2011 Harley-Davidson FLTRX Road Glide Custom custom - cruiser motorcycle, Harley-Davidson utilizes a 1573.3 cc (96 cu in) air-cooled v2, four-stroke layout. In factory specification, maximum torque reaches 126 Nm (92.9 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 98.4 x 111.3 mm (3.9 x 4.4 inches) with a 9.6:1 compression ratio.
On the scales, the FLTRX Road Glide Custom measures 350.2 kg (772 lbs) dry. Rider ergonomics and chassis geometry center around a 688 mm (27.1 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 22.7-liter (6 US gal) fuel tank paired with a rated consumption of 5.29 L/100 km provides an estimated theoretical range of roughly 429 km (267 miles) between fill-ups.
