The most fun per dollar in motorcycling, provided you check the oil and keep an eye on the dealer network.

New colours and a lower $5,899 US price for 2026, down from $6,299 at the 2024 launch. Hardware is unchanged from the 2024 redesign with the 399cc engine, new frame, and WP Apex suspension.

The review

Five parts, no spec-sheet copying.

A single teaches you rhythm. Every gear change is a decision, and the bike tells you immediately whether it was the right one.

Mechanical Breakdown

The third-generation 390 Duke grew to 399cc with a longer stroke and picked up a new steel trellis frame with a bolt-on aluminium subframe. The single is mounted as a stressed member and the 43 mm WP Apex open-cartridge fork is adjustable for compression and rebound, which is unheard of at this price.

You also get cornering ABS, traction control, a supermoto mode, a bidirectional quickshifter as an option, and a 5-inch TFT. The 320 mm front disc with a four-piston ByBre caliper is the strongest brake in the class.

Ride Character

A single-cylinder engine has a personality a twin never will. The 390 pulls hard from 5,000 rpm with a thump you feel in your chest, and the chassis is so light and sharp that it changes direction faster than you can think. It flatters an intermediate rider and can frighten a true novice, mostly through its speed of steering rather than its power.

The seat is firm and 820 mm tall, and the single vibrates above 8,000 rpm. Neither bothered me; both might bother you.

Maintenance Outlook

KTM singles ask for oil changes every 7,500 km and valve checks at 15,000 km, and I would shorten both. The engine runs hot in traffic and the oil level needs watching. The good news is that everything is exposed: no fairing, easy filter access, and a well-documented owner community.

The caution is the corporate story. KTM's 2025 restructuring and Bajaj's takeover mean parts and dealer support are worth checking locally before you buy.

Who It's For

The beginner who has already ridden a scooter or a small bike and wants their first motorcycle to be an event. Also the best pick here for anyone who lives on twisty roads rather than highways.

Jun's Verdict

The 390 Duke is the beginner bike I would buy for myself, and I say that knowing its service intervals are shorter and its dealer network is thinner. The fork, the brake, and the electronics are genuinely from a class above. Just read the manual and check the oil like it is a ritual.
