Built around Harley-Davidson's custom - cruiser motorcycle platform, the 2004 Harley-Davidson FXDI Dyna Super Glide features a 1449 cc (88.4 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 67 HP (48.9 kW) while maximum torque reaches 102 Nm (75.2 lb-ft) at 3,400 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 46.2 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the FXDI Dyna Super Glide measures 301 kg (664 lbs) wet (curb), translating to a power-to-weight ratio of 0.22 HP/kg (4.49 kg per horsepower). Rider ergonomics and chassis geometry center around a 713 mm (28.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,595 mm (62.8 in) wheelbase engineered for planted straight-line stability. The 17.8-liter (4.7 US gal) fuel tank paired with a rated consumption of 6.5 L/100 km provides an estimated theoretical range of roughly 274 km (170 miles) between fill-ups, while factory top speed is listed at 160 km/h (99 mph).
