The KTM 390 Duke is a 349.32 cc liquid-cooled motorcycle with a 6-speed gearbox. KTM's own India model-lineup page lists 41.5 PS @ 8600 rpm maximum power and 33.5 Nm @ 7000 rpm maximum torque — a lower state of tune than the separately-catalogued 390 Duke R (398.63 cc, 46 PS), confirmed as a genuinely different current KTM India model, not a data error. BikeWale corroborates the same displacement, power and torque exactly, and adds a Supermoto ABS, disc brakes at both ends, a 15 litre fuel tank and a 168.3 kg kerb weight.
The KTM Duke 390 is a motorcycle from KTM. It is currently on sale. With a 398.7 cc engine it sits in the 250–450 cc class.
Power comes from a 398.7 cc liquid-cooled engine that makes 41.5 PS at 8,600 rpm and 33.5 Nm of torque at 7,000 rpm. Its bore is wider than its stroke (89.0 x 60.0 mm), a short-stroke layout that generally favours higher revs. Divide power by kerb weight and it has about 247 PS per tonne; by that measure, it is lively, with easy overtakes and relaxed highway speeds. The claimed top speed is 160 km/h. It has electric start.
It has a 6-speed manual gearbox, and a chain carries drive to the rear wheel. Its slipper clutch lightens the lever and stops the rear wheel hopping when you downshift hard.
It is built around a Split-Trellis frame. At the front, the suspension is adjustable (5-step damping), inverted telescopic fork, 43mm dia (open cartridge). At the rear, it is adjustable (5-step damping), monoshock, 10-step preload adjustable. Braking is by a disc at the front and a disc at the rear. It rides on 17-inch alloy wheels with tubeless tyres — 110/70 - ZR 17 M/C at the front and 150/60 - ZR 17 M/C at the rear.
The seat is 800 mm off the ground, which is about average and suits most riders. It weighs 168.3 kg ready to ride. Ground clearance is 183 mm — enough for most speed breakers. It is 2,002 mm long, with 1,354 mm between the axles. It carries 15 L of fuel.
Equipment includes a digital instrument console.

Mechiee doorstep service
₹2,199
Mechiee's fixed doorstep service price for this model.
Follow the schedule in the owner's manual for your exact variant and year. A regular service is the cheapest way to catch small problems before they become expensive ones.
Engine oil is the single most important consumable to keep fresh. Top up between services if the level drops, and change it on schedule.
With Disc and Disc brakes, check pad or shoe wear, lever and pedal free play, and braking feel at every service.
A clean, correctly tensioned and lubricated chain lasts longer and wastes less power. Check slack regularly, especially after riding in rain or dust.
A liquid-cooled engine relies on coolant. Check the level and look over hoses and the radiator for leaks or damage, and replace coolant as the owner's manual directs.
A clogged air filter or worn spark plug shows up as hard starting, weak throttle response and poorer fuel economy. Both are checked at a regular service and replaced when worn.
Brake fluid absorbs moisture over time, which lowers its boiling point. Have its level and condition checked and change it on the interval in the owner's manual.
This bike runs 110/70 - ZR 17 M/C / 150/60 - ZR 17 M/C tyres. Check pressure, tread depth and sidewalls, and replace tyres that are worn or cracked.
The battery is listed as 12V, 8Ah. Weak starting, dim lights or a flickering console are early signs the battery or charging system needs a look.
