2021 Harley-Davidson Iron 1200 Technical Analysis & Specification Breakdown
Built around Harley-Davidson's custom - cruiser motorcycle platform, the 2021 Harley-Davidson Iron 1200 utilizes a 1202 cc (73.4 cu in) air-cooled v2, four-stroke layout. In factory specification, maximum torque reaches 99 Nm (73 lb-ft) at 3,500 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 88.9 x 96.8 mm (3.5 x 3.8 inches) with a 10.0:1 compression ratio.
On the scales, the Iron 1200 measures 255.8 kg (564 lbs) wet (curb). 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 1,514 mm (59.6 in) wheelbase engineered for balanced agility and highway composure. The 12.5-liter (3.3 US gal) fuel tank paired with a rated consumption of 4.9 L/100 km provides an estimated theoretical range of roughly 255 km (158 miles) between fill-ups.
