Built around Harley-Davidson's custom - cruiser motorcycle platform, the 2006 Harley-Davidson FLST Heritage Softail pairs a 1442.2 cc (88 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, maximum torque reaches 115.3 Nm (85 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 95.3 x 101.6 mm (3.8 x 4.0 inches) with a 8.9:1 compression ratio.
On the scales, the FLST Heritage Softail measures 318.9 kg (703 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 1,638 mm (64.5 in) wheelbase engineered for planted straight-line stability. The 18.92-liter (5 US gal) fuel tank paired with a rated consumption of 5 L/100 km provides an estimated theoretical range of roughly 378 km (235 miles) between fill-ups.
