Bajaj Auto has once again redefined performance biking with the launch of the 2025 Pulsar NS400Z UG, a machine that builds on its legacy while introducing significant mechanical upgrades and sharper performance. Priced at ₹1.92 lakh (ex-showroom), this latest iteration is ₹7,000 costlier than the previous model, but the added value more than justifies the price hike. In fact, the 2025 NS400Z retains its crown as the most value-for-money (VFM) motorcycle in the 350cc to 500cc category.
The biggest highlight of the 2025 NS400Z is the performance upgrade. Bajaj has retained the tried-and-tested 373cc single-cylinder, liquid-cooled engine, but it has been tuned to deliver 43 PS of peak power, up from 40 PS. This enhanced power output is paired with 35 Nm of peak torque, ensuring the bike feels more aggressive and responsive across the rev range. The refinement and performance improvements are not just on paper — the 0-60 km/h acceleration now clocks in at 2.7 seconds, significantly quicker than the previous 3.2 seconds. Similarly, the 0-100 km/h time is now 6.4 seconds, a notable drop from the earlier 7.5 seconds. The top speed has also increased to 157 km/h, making this version of the NS400Z the fastest yet.
One of the most rider-centric upgrades is the addition of a bi-directional quick-shifter. This feature allows for seamless gear shifts without needing to engage the clutch, adding a sporty and track-ready feel that was previously unavailable in this price bracket. The existing 6-speed gearbox and slipper clutch setup continue to offer smooth transitions, especially helpful during aggressive downshifting.
Beyond the powertrain, Bajaj has made subtle yet important improvements to enhance braking and traction. The 2025 Pulsar NS400Z now comes with sintered brake pads, known for their superior bite and heat resistance. This upgrade translates into sharper braking feedback and better control under both city and highway riding conditions.
In terms of design and ergonomics, the NS400Z retains its muscular streetfighter stance. The LED projector headlamp, split-seat setup, perimeter frame, and split rear grab rails remain unchanged, offering a familiar yet aggressive aesthetic. The 43mm USD front forks finished in a premium golden shade, combined with the rear mono-shock suspension, provide commendable stability and comfort, even on uneven roads.
The cockpit also maintains its modern appeal, with a fully digital instrument cluster that offers Bluetooth connectivity and turn-by-turn navigation. These features, while already available in the previous model, remain relevant and competitive in 2025. The digital display is intuitive and keeps riders informed without clutter or confusion.
Despite these enhancements, Bajaj has opted not to add new cosmetic features or extensive hardware changes, focusing instead on refining the core elements that riders value most — performance, control, and ride quality.
What truly sets the 2025 NS400Z apart is how it manages to offer premium-level performance and tech at a price point significantly lower than most of its rivals. Motorcycles in the 400cc segment often breach the ₹2 lakh mark, and with the NS400Z staying just under that barrier, it continues to appeal strongly to both new buyers and seasoned enthusiasts.
In a market where price hikes often bring negligible upgrades, Bajaj has taken the opposite route. With meaningful changes to power delivery, braking feedback, and ride quality, the 2025 Bajaj Pulsar NS400Z UG stands as a benchmark of performance evolution. It’s a rare case where a modest price hike results in a motorcycle that feels genuinely more complete and more thrilling than its predecessor.
For enthusiasts seeking a capable machine for city commutes, weekend rides, and occasional highway bursts, the NS400Z remains an unbeatable proposition. Its updated quick-shifter, better acceleration, and improved braking components only sweeten the deal further.
The Pulsar NS400Z UG 2025 isn’t just a refresh — it’s a well-calculated upgrade that builds on the strengths of the platform while addressing key feedback from riders. With these enhancements, Bajaj has once again set the bar high for performance motorcycles in the sub-2 lakh segment. And with no direct competitor offering this level of performance, technology, and brand trust at this price point, the NS400Z is poised to maintain its stronghold well into the next year.
