Bajaj Pulsar NS400 Review: High-Performance 373cc Streetfighter Worth the Price?

The Bajaj Pulsar NS400 enters the Indian 400cc-class motorbike segment as a street-fighter that promises serious punch without burning a hole in your wallet. With a 373cc liquid-cooled engine, updated 2025 spec-sheet and aggressive styling, Pulsar NS400 aims to deliver performance, practicality and modern tech — a compelling mix for riders seeking a powerful yet value-for-money 400cc ride.

Engine & Performance

Pulsar NS400 is powered by a 373.3 cc single-cylinder, liquid-cooled engine — borrowed and retuned from the stable of larger Bajaj/partner bikes. In the 2025 update (NS400Z), the company has further tuned the engine to bump power up from earlier ~40 PS to about 43 PS and retained 35 Nm torque. Paired with a 6-speed gearbox and an assist-and-slipper clutch, the bike now delivers a sharper throttle response and quicker acceleration.

Thanks to these upgrades, the 0–60 km/h sprint reportedly takes just 2.7 seconds, and 0–100 km/h in around 6.4 seconds, while claimed top-speed rises to 157 km/h. This makes NS400 one of the fastest Pulsars available — good for riders who want real-world performance for both city bursts and highway runs.

Chassis & Handling

Chassis-wise, NS400 uses a perimeter frame to ensure rigidity and stability. At the front, it rides on 43 mm upside-down (USD) forks, while the rear gets a preload-adjustable monoshock — a setup that balances sporty handling with acceptable comfort even over imperfect Indian roads.

Braking duties are handled by a 320 mm front disc and a 230 mm rear disc, both backed by dual-channel ABS. With a kerb weight of about 174 kg, the bike remains manageable enough for urban traffic without compromising on stability at higher speeds.

Technology & Features

NS400 comes loaded with features that are rare in its price bracket. It offers a full-digital colour TFT instrument cluster with Bluetooth connectivity, navigation, call and SMS alerts — thanks to the “Ride Connect” system. It also brings ride-by-wire throttle and riding modes (Road, Rain, Sport, Off-road/Track depending on variant), along with switchable traction control and dual-channel ABS to match. 

Lighting is fully LED: a projector headlamp with signature DRLs, and LED tail-lamp and indicators, giving NS400 modern streetfighter looks. These features combined — powerful engine, modern electronics, dynamic styling — make the NS400 a well-rounded package.

Conclusion

Overall, Bajaj Pulsar NS400 brings together commendable power delivery, competent chassis dynamics and modern-day features at a value-driven price point. It is ideal for riders who want a 400 cc-class streetfighter suitable for daily commuting, spirited city rides, and occasional highway bursts — without splurging on premium bikes. For someone seeking a blend of performance, practicality and modern features in one package, Pulsar NS400 represents strong value. In short: if you want a powerful, feature-rich 400cc ride that doesn’t break the bank, the NS400 is certainly worth your consideration.
