2021 Harley-Davidson Street 500 Technical Analysis & Specification Breakdown
Engineered by Harley-Davidson for the custom - cruiser motorcycle segment, the 2021 Harley-Davidson Street 500 utilizes a 491.6 cc (30 cu in) liquid-cooled v2, four-stroke layout. In factory specification, maximum torque reaches 40 Nm (29.5 lb-ft) at 3,500 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 69.1 x 66.0 mm (2.7 x 2.6 inches) with a 11.0:1 compression ratio.
On the scales, the Street 500 measures 233 kg (514 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 720 mm (28.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,520 mm (59.8 in) wheelbase engineered for balanced agility and highway composure. The 13.25-liter (3.5 US gal) fuel tank paired with a rated consumption of 3.68 L/100 km provides an estimated theoretical range of roughly 360 km (224 miles) between fill-ups.
