At the heart of the 2019 Harley-Davidson Road Glide touring motorcycle, Harley-Davidson pairs a 1746 cc (106.5 cu in) oil & air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 89 HP (65 kW) at 5,450 rpm while maximum torque reaches 150 Nm (110.6 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 51 HP per liter and a 2,200 rpm working window between peak torque (3,250 rpm) and peak power (5,450 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Road Glide measures 388 kg (855 lbs) wet (curb), translating to a power-to-weight ratio of 0.23 HP/kg (4.36 kg per horsepower). Rider ergonomics and chassis geometry center around a 658 mm (25.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,625 mm (64 in) wheelbase engineered for planted straight-line stability. The 22.71-liter (6 US gal) fuel tank paired with a rated consumption of 5.9 L/100 km provides an estimated theoretical range of roughly 385 km (239 miles) between fill-ups.

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.
Suspension
Suspension details can matter for comfort, road feel and long-distance riding.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
