Dimensions in practice
The 390 Duke R weighs 168.3 kg with fluids, has an 820 mm seat, 183 mm of ground clearance, and rides on a 1357 mm wheelbase. That clearance is generous: speed breakers and broken roads will not trouble the underbody.
The fuel tank holds 15 litres, good for about 428 km between fills in real-world riding.
Tyres are 110/70-ZR17 front and 150/60-ZR17 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.
Chassis
Alloy wheels
Lighter than spoked wheels and they allow tubeless tyres.
USD front forks
Stiffer than conventional forks, so the front feels planted under hard braking.
Rear monoshock
One central shock instead of twin units; usually better damping on broken roads.
Slipper clutch
Stops the rear wheel hopping on aggressive downshifts. Also makes the lever lighter.
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.
Console and connectivity
Colour TFT console
Readable in direct sun and can show turn-by-turn navigation.
Digital console
Trip meters, real-time mileage and a gear indicator. The analogue dial is disappearing.
Bluetooth connectivity
Call and message alerts on the console so the phone stays in your pocket.
Turn-by-turn navigation
Directions on the console via the phone app. Saves mounting a phone on the bars.
Ride modes
An Eco map for mileage and a Power map for overtakes, switched from the bars.
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.
