Key design elements include hyper-sharp tank extensions, split LED headlights, and an edgy tail design that gives it a distinctive “train appearance”.

The bike’s frame and subframe have been optimized not just for aesthetics but also to improve its directness on the road.

 Its bare trellis frame, combined with vibrant paint jobs and high-quality art and finish, makes the Duke 390 an undeniable head-turner, even when standing still. The aggressive styling emphasizes its performance capabilities, hinting at the power that lies beneath its sleek exterior.

Engine & Performance

The 2024-Duke 390 introduces significant changes in its engine, establishing it as a top contender in its class. KTM has increased the engine’s capacity from 373 cc to a more potent 398.7cc. 

This upgrade results in more power and smoother delivery, enhancing the overall riding experience. The engine now churns out an impressive 46 PS and 39 Nm of torque, promising an even more exhilarating ride.

The inclusion of a ride-by-wire throttle control ensures precise throttle response. Additionally, smooth, clutchless gear changes are made possible, contributing to a fluid and engaging ride.

This combination of increased capacity, power, and refined controls underscores KTM’s commitment to delivering a high-performance motorcycle.

The ergonomics of the Duke 390 are designed for versatility. Its upright riding style, wide handlebar, and a more comfortable seat make it suitable for both short commutes and longer rides. For braking, the bike comes standard with ByBre disc brakes and dual-channel ABS, ensuring strong and reliable stopping power.

Mileage / Fuel Economy

Performance bikes like the Duke 390 are not primarily designed for extreme fuel efficiency, and the 2025 model is no exception. KTM estimates that the Duke 400 (referring to the Duke 390 with its increased capacity) should deliver approximately 27-30 kmpl. However, actual mileage can vary based on several factors, including individual riding style (whether it’s frequent spirited rides or more relaxed weekend cruising) and traffic conditions.

The Duke 390 is equipped with a 15-liter fuel tank. This capacity, combined with the estimated mileage, suggests a medium range of around 400 km on a full tank. This range makes it a reasonably useful option for weekend rides or longer trips, provided riders are prepared for premium fuel and regular servicing.

Price & Variants

As of 2024, the KTM Duke 390 (2025 model) is priced around ₹3.11 lakhs (ex-showroom). At the time of its release, only one variant is available. However, KTM has a history of introducing limited editions in the future, so additional variants might be released later.

While the price might seem substantial, the performance, distinctive design, and the array of added features significantly outweigh the cost. The Duke 390 is often described as more than just a bike; it’s an experience. This reflects the brand’s commitment to delivering a premium product that justifies its price point through a comprehensive package of power, style, and technology.

Final Verdict

The KTM Duke 390 solidifies its position among the “under 400cc legends,” standing out as a true beast in its segment.
