The KTM 125 Duke (also 125 Duke) is a discontinued 124.7 cc liquid-cooled motorcycle with a 6-speed gearbox. BikeDekho and ZigWheels agree exactly on power (14.5 PS @ 9250 rpm), torque (12 Nm @ 8000 rpm), bore/stroke and 110/70-R17 front / 150/60-R17 rear tyres. Where they disagreed on ground clearance, fuel tank and kerb weight, BikeDekho's figures are used, since ZigWheels' conflicting numbers on those fields exactly match a different KTM Duke model.
The KTM Duke 125 is a naked motorcycle from KTM. It has been discontinued. Mechiee still services it at your doorstep. Naked and roadster bikes pair a lively engine with an upright riding position and little or no fairing, which makes them easy to live with every day. With a 124.7 cc engine it sits in the 125–150 cc class.
Power comes from a 124.7 cc single-cylinder liquid-cooled fuel-injected engine that makes 14.5 PS at 9,250 rpm and 12 Nm of torque at 8,000 rpm. Its bore is wider than its stroke (58 mm x 47.2 mm), a short-stroke layout that generally favours higher revs. Divide power by kerb weight and it has about 98 PS per tonne; by that measure, there is enough go for confident city riding and relaxed highway cruising. The claimed top speed is 107 km/h. It has electric start.
It has a 6-speed manual gearbox with a 1-down, 5-up shift pattern. It uses a wet multi-plate clutch.
It is built around a steel trellis frame. Suspension is by telescopic fork at the front and monoshock at the rear. Braking is by a 300 mm disc at the front and a 230 mm disc at the rear, with single-channel ABS. Single-channel ABS works on the front wheel, which does most of the stopping. It rides on 17-inch alloy wheels with tubeless tyres — 110/70-R17 at the front and 150/60-R17 at the rear.
The seat is 818 mm off the ground, which is about average and suits most riders. It weighs 148 kg ready to ride. Ground clearance is 175 mm — enough for most speed breakers. It is 1,993 mm long, with 1,366 mm between the axles. Its 10.2 L fuel tank and claimed mileage of 46.92 kmpl work out to roughly 479 km per tankful on paper; real-world range is usually lower.
Equipment includes a digital instrument console, a halogen headlamp, gear position indicator, average speed indicator, daytime running lamps, low oil indicator, low battery indicator, slipper clutch, engine start/stop button and adjustable rear preload. Safety equipment includes engine kill switch, side-stand warning, hazard light switch and automatic headlamp on.

Mechiee doorstep service
₹899
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, 300 mm and Disc, 230 mm 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-R17 / 150/60-R17 tyres. Check pressure, tread depth and sidewalls, and replace tyres that are worn or cracked.
Weak starting, dim lights or a flickering console are early signs the battery or charging system needs a look.
