Design Comparison
The Bajaj Pulsar NS400Z carries a new-age design that aligns with its NS and N series motorcycles. The design is attractive, featuring a new LED headlamp with DRLs, sharp body lines, sculpted tail section, premium naked-bike elements, and USD front forks, and is likely to attract a wide range of buyers.

KTM, on the other hand, offers a sharp and sleek design that follows its global design language, one that has evolved over the years yet still looks fresh and appealing. Features such as the LED headlamp, muscular fuel tank, split seats, sharp tail section, aggressive edges, and vibrant colour options come together to give it a sporty, almost supersport-like presence. Overall, while the Bajaj Pulsar NS400Z impresses with its bold design, the KTM Duke 390 looks more premium and sets the design benchmark in its segment.

The Bajaj Pulsar NS400Z uses the previous-generation engine from the KTM Duke 390, a 373.27cc single-cylinder unit. Its power output is lower compared to the latest Duke 390, which produces a strong 46 PS of power and nearly 40 Nm of torque.
That said, the Pulsar NS400Z remains an engaging motorcycle to ride, especially in city conditions where its strong low- and mid-range torque plays a bigger role. However, when it comes to outright performance and overall capability, the KTM Duke 390 stands out as the ultimate machine in the segment.
