Dyna Street Bob

2015 Harley-Davidson Dyna Street Bob Technical Analysis & Specification Breakdown

At the heart of the 2015 Harley-Davidson Dyna Street Bob custom - cruiser motorcycle, Harley-Davidson features a 1690 cc (103.1 cu in) air-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 76.4 HP (55.8 kW) at 5,250 rpm while maximum torque reaches 130 Nm (95.9 lb-ft) at 3,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 45.2 HP per liter and a 2,250 rpm working window between peak torque (3,000 rpm) and peak power (5,250 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the Dyna Street Bob measures 304.8 kg (672 lbs) wet (curb), translating to a power-to-weight ratio of 0.25 HP/kg (3.99 kg per horsepower). Rider ergonomics and chassis geometry center around a 648 mm (25.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,631 mm (64.2 in) wheelbase engineered for planted straight-line stability. The 17.79-liter (4.7 US gal) fuel tank paired with a rated consumption of 5.47 L/100 km provides an estimated theoretical range of roughly 325 km (202 miles) between fill-ups.
