Positioned in Harley-Davidson's custom - cruiser motorcycle lineup, the 2006 Harley-Davidson FLSTC Heritage Softail Classic relies on a 1442.2 cc (88 cu in) air-cooled v2, four-stroke powerplant. 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 FLSTC Heritage Softail Classic measures 340.2 kg (750 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 648 mm (25.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with 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 5.34 L/100 km provides an estimated theoretical range of roughly 354 km (220 miles) between fill-ups.
