FLHX Street Glide

2008 Harley-Davidson FLHX Street Glide Technical Analysis & Specification Breakdown

Engineered by Harley-Davidson for the touring motorcycle segment, the 2008 Harley-Davidson FLHX Street Glide utilizes a 1573.3 cc (96 cu in) air-cooled v2, four-stroke layout. In factory specification, peak output is rated at 87 HP (63.5 kW) at 5,450 rpm while maximum torque reaches 125.6 Nm (92.6 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 55.3 HP per liter and a 1,950 rpm working window between peak torque (3,500 rpm) and peak power (5,450 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the FLHX Street Glide measures 356.5 kg (786 lbs) wet (curb), translating to a power-to-weight ratio of 0.24 HP/kg (4.1 kg per horsepower). Rider ergonomics and chassis geometry center around a 693 mm (27.3 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 22.71-liter (6 US gal) fuel tank paired with a rated consumption of 4.35 L/100 km provides an estimated theoretical range of roughly 522 km (324 miles) between fill-ups.
