2015 Harley-Davidson Sportster Iron 883 Technical Analysis & Specification Breakdown
Built around Harley-Davidson's custom - cruiser motorcycle platform, the 2015 Harley-Davidson Sportster Iron 883 features a 883.3 cc (53.9 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 52.3 HP (38.2 kW) at 5,750 rpm while maximum torque reaches 73 Nm (53.8 lb-ft) at 3,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 59.2 HP per liter and a 2,000 rpm working window between peak torque (3,750 rpm) and peak power (5,750 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Sportster Iron 883 measures 260 kg (573 lbs) wet (curb), translating to a power-to-weight ratio of 0.2 HP/kg (4.97 kg per horsepower). Rider ergonomics and chassis geometry center around a 653 mm (25.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,519 mm (59.8 in) wheelbase engineered for balanced agility and highway composure. The 12.49-liter (3.3 US gal) fuel tank paired with a rated consumption of 4.61 L/100 km provides an estimated theoretical range of roughly 271 km (168 miles) between fill-ups.
