Bajaj Auto has officially updated its flagship streetfighter, the Pulsar NS400Z, with a new 350cc engine. This strategic shift follows recent changes in Indian taxation (GST 2.0), moving the motorcycle into a more favorable tax bracket while maintaining its status as one of the most affordable performance bikes in the country.
Key Specifications: What’s New?
The core update is a downsized engine, shared with the recently updated Dominar 400. The displacement has been reduced from 373cc to 349.13cc by shortening the stroke (now 56.1mm) while keeping the same 89mm bore.
| Feature | New 350cc Version | Previous 373cc Version |
| Displacement | 349.13cc | 373.27cc |
| Peak Power | 40.6 PS @ 9,000 rpm | 43 PS @ 8,800 rpm |
| Peak Torque | 33.2 Nm @ 7,500 rpm | 35 Nm @ 6,500 rpm |
| Engine Character | Rev-happy, “peaky” delivery | Torque-heavy, linear delivery |
Performance Note: While there is a slight dip of 2.4 PS and 1.8 Nm, the revised engine delivers its peak output higher in the rev range. This suggests a more aggressive, high-revving character for the NS400Z compared to the more relaxed feel of the outgoing unit.
Design and Features
Visually, the NS400Z remains identical to the previous model. Bajaj has chosen not to alter the aggressive “NS” styling that features a muscular fuel tank, sharp LED headlamps, and a compact tail section.
Continuing Features:
-
Ride-by-Wire: Four riding modes (Road, Rain, Sport, and Off-road) that adjust power delivery and ABS sensitivity.
-
Hardware: 43mm Gold USD (Upside Down) front forks and a Nitrox rear monoshock.
-
Electronics: LCD console with Bluetooth connectivity, turn-by-turn navigation, and switchable Traction Control.
-
Brakes: 320mm front disc and 230mm rear disc with dual-channel ABS.
Price and Market Position
Despite the engine transition, Bajaj has kept the ex-showroom price steady, reinforcing its value-for-money appeal.
-
Launch Price: ₹1,93,900 (Ex-showroom, Delhi).
-
Color Options: Brooklyn Black, Pearl Metallic White, Glossy Racing Red, and Pewter Grey.
Why the Change?
The shift to a sub-350cc engine allows the NS400Z to move from a 40% GST bracket to an 18% GST bracket. While some models (like the Dominar 400) saw a significant price cut following this change, Bajaj has opted to keep the NS400Z’s price unchanged, likely to offset the costs of integrating the newer, more efficient engine and advanced features.
The Verdict
The 2026 Bajaj Pulsar NS400Z remains a powerhouse in the sub-2 lakh segment. While enthusiasts may miss the raw torque of the 373cc engine, the new 350cc motor promises a more engaging, high-revving experience that aligns the bike with the latest KTM and Triumph models in the Bajaj ecosystem.
