The 2026 update of the Bajaj Pulsar NS400Z brings a subtle but significant shift under the skin. While the motorcycle looks identical to its predecessor, Bajaj has revised the engine, slightly altering the bike’s performance character without changing its overall positioning.
Smaller engine, slightly lower output
The biggest change comes in the form of a downsized engine. The earlier 373cc motor has been replaced by a 349.13cc, single-cylinder, liquid-cooled unit. This has resulted in a marginal drop in output, with power now rated at 40 bhp and torque at 33.2 Nm.
To achieve this, Bajaj reduced the engine’s stroke length while keeping the bore unchanged. The result is a motor that revs similarly but delivers a slightly toned-down punch compared to the outgoing version. Interestingly, the new output figures are close to what the bike produced when it was first introduced, before later updates boosted its performance.

No changes to design and hardware
Apart from the engine revision, the rest of the motorcycle remains untouched. The Pulsar NS400Z continues with its aggressive streetfighter styling and is offered in the same four colour options.
The hardware setup also stays the same. It is built on a perimeter frame and uses upside-down front forks along with a rear monoshock. The bike rides on 17-inch alloy wheels, with braking handled by disc brakes at both ends.
Bajaj has retained the NS400Z’s strong feature list, which includes Bluetooth connectivity, navigation support and multiple riding modes. Riders also get a quickshifter and traction control, features that add to its appeal in the segment.

Same price, different character
Despite the mechanical tweak, pricing remains unchanged at around ₹1.93 lakh (ex-showroom). This makes the update more about refinement and repositioning rather than a complete overhaul.
For buyers, the decision will come down to whether the slightly reduced performance impacts the riding experience. On paper, the changes are minor, but on the road, the new engine could offer a smoother and more manageable delivery, especially for everyday use.
