At the heart of the 2008 Harley-Davidson FLSTN Softail Deluxe custom - cruiser motorcycle, Harley-Davidson features a 1573.3 cc (96 cu in) air-cooled v2, four-stroke configuration. In factory specification, maximum torque reaches 120 Nm (88.5 lb-ft) at 3,300 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 95.3 x 111.3 mm (3.8 x 4.4 inches) with a 9.2:1 compression ratio.
On the scales, the FLSTN Softail Deluxe measures 328.4 kg (724 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 658 mm (25.9 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 4.35 L/100 km provides an estimated theoretical range of roughly 435 km (270 miles) between fill-ups.
