Breakout

2021 Harley-Davidson Breakout Technical Analysis & Specification Breakdown

Built around Harley-Davidson's custom - cruiser motorcycle platform, the 2021 Harley-Davidson Breakout relies on a 1868 cc (114 cu in) air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 93 HP (67.9 kW) at 5,020 rpm while maximum torque reaches 155 Nm (114.3 lb-ft) at 3,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 49.8 HP per liter and a 1,770 rpm working window between peak torque (3,250 rpm) and peak power (5,020 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the Breakout measures 305 kg (672 lbs) wet (curb), translating to a power-to-weight ratio of 0.3 HP/kg (3.28 kg per horsepower). Rider ergonomics and chassis geometry center around a 665 mm (26.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,695 mm (66.7 in) wheelbase engineered for planted straight-line stability. The 13.2-liter (3.5 US gal) fuel tank paired with a rated consumption of 5.47 L/100 km provides an estimated theoretical range of roughly 241 km (150 miles) between fill-ups.
