Harley-Davidson Fat Boy specifications and features
Every figure from the manufacturer's sheet, plus what each feature actually does for you.
Engine and performance
Power comes from a 1868cc single producing 93.87 bhp and 155 Nm, paired with a 6 Speed. At 317 kg the power-to-weight figure is 296 bhp per tonne, which ranks 23 of 51 in its class here.
Torque is high relative to peak power, which is what you want for pulling away with a pillion and riding a gear higher in traffic rather than chasing the redline.

Dimensions in practice
The Fat Boy weighs 317 kg with fluids, has an 675 mm seat, 115 mm of ground clearance, and rides on a 1665 mm wheelbase. Clearance is on the low side; take tall speed breakers at an angle with a pillion.
The fuel tank holds 18.9 litres.
Tyres are 160/60-R18 front and 240/40-R18 rear, tubeless.
Features, and why each matters
Grouped by what they do for you. Underlined items link to a plain-English explainer.
Safety and braking
Stops both wheels from locking under panic braking. The single biggest safety upgrade on a two-wheeler.
Front disc brake
Sheds heat and works when wet. Worth the small premium over a drum on any commuter.
Rear disc brake
Adds feel and fade resistance at the back; matters more on heavier or faster bikes.
Tubeless tyres
A puncture deflates slowly instead of instantly, and roadside repair takes ten minutes.
Traction control
Cuts power if the rear spins on wet paint or gravel. Rare under ₹2 lakh.
Side-stand engine cut-off
Engine will not run with the stand down, which prevents a common low-speed crash.
Hazard lamps
All four indicators flash; useful in fog and when stopped on a highway shoulder.
Console and connectivity
Digital console
Trip meters, real-time mileage and a gear indicator. The analogue dial is disappearing.
Chassis
Alloy wheels
Lighter than spoked wheels and they allow tubeless tyres.
Rear monoshock
One central shock instead of twin units; usually better damping on broken roads.
Lighting
LED headlamp
Brighter, whiter and lasts the life of the bike. Halogens on rivals look yellow by comparison.
LED daytime running lamp
Makes you visible to cars in daylight, when most two-wheeler collisions happen.
LED tail lamp
Lights up instantly, which gives the vehicle behind a fraction more warning.
Convenience
USB charging port
Charges the phone on a long commute. Check whether it is Type-A or Type-C.
Engine kill switch
Switch the engine off from the right bar without reaching for the key.
Equipment against Breakout, Fat Bob and Street Glide
What it lacks: slipper clutch and ride modes, which rivals at this price offer. None of these are deal-breakers, but they show where the money went.
It is offered in 4 colours: Blue Burst, Billiard Gray, Vivid Black and Whiskey Fire/Vivid Black. Colour availability varies by variant and dealer stock.
