KTM 390 Duke: A2 category naked motorcycle, generations and what to check
KTM 390 Duke — a lightweight, lively naked motorcycle with a single-cylinder engine, popular among A2 category riders since 2013. We look at the generations, tech, and what to check when buying used.
390 Duke in brief
The KTM 390 Duke debuted in 2013 as a compact, lightweight, and agile motorcycle. It's known for its lively character, easy handling, and that signature 'orange' KTM style.
With A2-compliant power and pricing, it's a hit with young riders. There's a vast selection of used examples on the market.
Generations — what sets them apart
The first generation (2013–2016) comes with basic equipment and classic KTM design. These bikes are more affordable but have already covered some miles.
The second generation (2017–2023) features a new frame, refined styling, and smartphone connectivity. The third generation (from 2024) boasts a slightly larger engine and modern electronics.
Engine and transmission
The first two generations have a 373 cm³ single-cylinder, liquid-cooled engine with around 44 hp (32 kW). The latest engine is 399 cm³, with around 46 hp.
The transmission is a 6-speed manual with a slipper clutch, driving the rear wheel via a chain. Most bikes come with ABS.
What to check when buying a used 390 Duke
Inspect the chain, sprockets, brakes, and tyres. Young riders often ride aggressively, so check for scratches, mirrors, footpegs, and tank scuffs.
Start the cold engine without assistance and listen for any unusual noises — a single-cylinder engine can vibrate. Check the valve clearances, cooling system, and ABS light.
Ask for the service history — single-cylinder engines require timely oil changes.
Trim levels
Names and equipment vary by market and year; we list the versions most commonly found in Europe.
