2026 Bajaj Pulsar NS400Z (349cc) Review – Downsized But Still The Best Bang For Your Buck

Last year, the central government revised the GST rates for two-wheelers along with a host of other vehicles and commodities. At the time of the announcement, Bajaj was one of the few major bikemakers in opposition to the motorcycle GST slabs as it brought its entire range of 350+cc performance motorcycles under the heavier 40% slab

However, with the government unwilling to change its mind on the matter, Bajaj went to work on downsizing its sub 400cc engines to meet the new sub 350cc class of motorcycles that attracts a much lower GST slab of 18%, including its own flagship, the Pulsar NS400Z.

To help it attract the lower 18% tax slab, Bajaj downsized the Pulsar NS400Z's engine from 373cc to 349.13cc which resulted in a noticeable cut in terms of pricing. The 373cc Bajaj Pulsar NS400Z was already one of the strongest value-for-money picks in the entry-level performance segment, and we rode the flagship Pulsar in Bangalore to see if the bang for your buck experience has been diluted by switching to the smaller engine.

2026 Bajaj Pulsar NS400Z (349cc) Review: What's Changed?

The only major change to the Pulsar NS400Z is its new 349.13cc unit. Bajaj brought the engine under the 350cc mark by switching to a shorter 56.1mm stroke, down from 60mm earlier, while the 89mm bore has been retained. Bajaj has also redesigned the crankshaft and altered the valve timings but retained the engine's 12.2:1 compression ratio.

The new 349cc Bajaj Pulsar NS400Z's engine now produces 40.6hp at 9,000rpm and 33.2Nm at 7,500rpm, down from 43hp and 35Nm that the 373cc motor kicked out. Peak torque on the new engine also arrives 1,000rpm later than before, making the new engine noticeably peakier.

Bajaj says 0-60km/h times remain unchanged at 2.8 seconds, but the 0-100km/h sprint now takes 6.8 seconds against the previous version's 6.5 seconds. The NS400Z's top speed has dropped marginally too.

Features carried over from the bigger-engined model include sintered brake pads, radial tyres, four riding modes and a software-based bi-directional quickshifter that still annoyingly still works only in Sport mode. The LCD display, switchgear and overall build quality remain identical to the outgoing bike.

2026 Bajaj Pulsar NS400Z (349cc) Review: Riding Impressions

The biggest change on the new Pulsar NS400Z is how the engine feels rather than what it looks like. The bike still feels refined, but the aggressive low-end character of the older 373cc motor has been toned down noticeably and this is something you will notice quite quickly once you start hitting the streets .

With torque now capped at 33.2Nm, the Pulsar NS400Z's initial acceleration doesn't have the same shove as before. Power delivery is smoother instead of punchy, and Bajaj's reworked throttle maps mean the transition from a lower-capacity motorcycle wouldn't feel jarring to a new rider.

The new Bajaj Pulsar NS400Z's performance picks up meaningfully past 7,000rpm, where the new 349cc engine comes alive and pulls strongly through to the top end. The mid-range is decent enough for highway overtakes and the outright top speed and overall performance stay close to what the 373cc bike offered.

Refinement has improved slightly over the outgoing bike, with no noticeable vibrations between 80-100kph on the highway and calmer running at cruising speeds. The exhaust note remains loud and sporty, and the quickshifter's rev-matched downshifts add to the experience.

Of the four ride modes, Road offers the most consistent and predictable throttle response and works best for everyday and stop-go riding. Sport sharpens throttle response for spirited riding and is the only mode that enables the quickshifter, though the response can feel abrupt at low speeds and switching between modes isn't the most intuitive process.

Rain mode smooths out power delivery for slippery roads, while Off-road shares Road's throttle map but disables the rear ABS to help you pull off some rather easily controllable slides.

The riding position remains one of the NS400Z's strengths, with a wide handlebar, slightly rear-set footpegs and an upright posture bringing a near perfect balance of sportiness and comfort. The short 1,346mm wheelbase and 176kg kerb weight keep direction changes quick, whether filtering through city traffic or through a sweeping set of turns on the open road.

The suspension setup remains quite good and the NS400Z absorbs ruts and bumps without ease. The one recurring complaint carried over from the 373cc bike is that the footpegs and belly pan (which have been retained as is) scrape too easily if you really try to lean into the turns.

Braking continues to be a strong point of the NS400Z, with the sintered brake pads offering good bite and progression allowing you to scrub off speed confidently. ABS intervention across the four ride modes is well calibrated and doesn't feel intrusive during hard braking.

The Bajaj Pulsar NS400Z's LCD display looks dated next to newer rivals, though Bluetooth connectivity and ride information are laid out clearly enough to use on the move. Our unit seemed to be suffering from some Bluetooth issue that did not allow us to connect the bike to our phones.

2026 Bajaj Pulsar NS400Z (349cc) Review: Verdict & Final Thoughts

The new Bajaj Pulsar NS400Z feels more refined and easier to ride than before, though riders familiar with the older 373cc version will notice the reduced low-end punch immediately. The chassis, brakes, suspension and riding ergonomics remain strong positives, and the four ride modes add further versatility to the package.

The sub 350cc Pulsar NS400Z is priced at Rs 1.82 lakh (ex-showroom, Delhi). Had Bajaj not downsized the engine, the motorcycle would have cost roughly Rs 30,000 more, which would have eroded its core value-for-money proposition.

Within its price bracket, the next motorcycle offering comparable 40hp performance is the Bajaj Dominar 400 at Rs 2.05 lakh, a heavier machine built for a much different purpose. The Triumph Tracker 400, the next relatively affordable 40hp option, costs Rs 2.46 lakh.

So for buyers looking for a practical, everyday performance motorcycle, the Bajaj Pulsar NS400Z continues to make a strong case at its price point as it continues to offer the best value for money at its price point.
