Built around Harley-Davidson's touring motorcycle platform, the 2015 Harley-Davidson Dyna Switchback utilizes a 1690 cc (103.1 cu in) air-cooled v2, four-stroke layout. In factory specification, peak output is rated at 75.1 HP (54.8 kW) at 5,000 rpm while maximum torque reaches 126 Nm (92.9 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 44.4 HP per liter and a 1,500 rpm working window between peak torque (3,500 rpm) and peak power (5,000 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Dyna Switchback measures 325.7 kg (718 lbs) wet (curb), translating to a power-to-weight ratio of 0.23 HP/kg (4.34 kg per horsepower). Rider ergonomics and chassis geometry center around a 663 mm (26.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,595 mm (62.8 in) wheelbase engineered for planted straight-line stability. The 17.79-liter (4.7 US gal) fuel tank paired with a rated consumption of 5.6 L/100 km provides an estimated theoretical range of roughly 318 km (198 miles) between fill-ups.

Use this page to compare this motorcycle by its real specifications, not only by model name. Focus on the details that affect fit, comfort, handling, range and ownership.
Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Seat Height
Check the seat height against your inseam and riding posture before choosing a motorcycle.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
