Built around Harley-Davidson's custom - cruiser motorcycle platform, the 2015 Harley-Davidson Sporster 1200 Custom relies on a 1201.25 cc (73.3 cu in) air-cooled air-cooled, evolution® powerplant. In factory specification, peak output is rated at 67.1 HP (48.9 kW) at 5,750 rpm while maximum torque reaches 96 Nm (70.8 lb-ft) at 3,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 55.8 HP per liter and a 2,000 rpm working window between peak torque (3,750 rpm) and peak power (5,750 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Sporster 1200 Custom measures 259.9 kg (573 lbs) wet (curb), translating to a power-to-weight ratio of 0.26 HP/kg (3.88 kg per horsepower). Rider ergonomics and chassis geometry center around a 676 mm (26.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1 mm (0 in) wheelbase engineered for quick, flickable steering geometry. The 2.8-liter (0.7 US gal) fuel tank paired with a rated consumption of 4.9 L/100 km provides an estimated theoretical range of roughly 57 km (35 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.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
