When Bajaj first hinted at a 400cc Pulsar, the internet lost its mind. For over two decades, the Pulsar name has been synonymous with accessible performance for Indian riders. From the original Pulsar 150 that rewrote the rules of affordable sporty commuting to the NS200 that gave enthusiasts a genuinely capable street fighter, every Pulsar has pushed boundaries. The NS400 pushes them further than ever before.
I’ve followed the development of this motorcycle closely, from the earliest spy shots to the production reveal, and I’ve spent enough time around Pulsar owners and Bajaj’s engineering philosophy to understand what this bike represents. It’s not just another model in the lineup—it’s Bajaj’s statement that Indian manufacturers can compete in the mid-capacity performance segment without charging European prices.
Let me break down everything you need to know about the Pulsar NS400, from what powers it to how it rides to whether it’s actually worth your money.
The Heart of the Machine: Engine and Performance
The engine is where the NS400 story begins, and it’s a fascinating piece of engineering. Bajaj borrowed heavily from the Dominar 400’s powerplant, which itself traces lineage to the KTM 390 platform. The 373cc single-cylinder, liquid-cooled, fuel-injected engine produces approximately 40 PS of peak power and around 35 Nm of torque.
Those numbers need context. Forty horsepower might not sound revolutionary when you consider that the KTM Duke 390 makes similar power. But the NS400’s engine character is distinctly different. Bajaj has retuned the ECU to deliver power in a more linear, accessible manner. Where the KTM engine can feel peaky and demanding, the NS400’s unit spreads its power more evenly across the rev range.
In practical riding terms, this means strong pulling power from around 3,500 RPM, building progressively through the mid-range and peaking around 8,500-9,000 RPM. There’s no dramatic hit of power that catches you off guard—just a smooth, relentless surge that feels faster than the numbers suggest.
The six-speed gearbox is slick enough for a bike in this price range. False neutrals are rare, the clutch pull is manageable in traffic, and the ratios are well-spaced for both city riding and highway cruising. The slipper clutch is a welcome addition, preventing rear-wheel hop during aggressive downshifts—a feature that was once reserved for much more expensive machines.
Top speed is reportedly in the region of 155-160 kmph, though real-world conditions rarely allow sustained riding at those velocities. What matters more is the cruising ability—sitting at 100-120 kmph feels effortless, with the engine barely breaking a sweat.
Design and Styling: The Pulsar DNA Evolved
The NS400 looks like a Pulsar that went to the gym and came back angry. Bajaj has maintained the aggressive street fighter stance that defines the NS lineage while adding visual bulk and premium details that justify the larger displacement.
The headlamp cluster features a projector setup with LED DRLs that create a distinctive face. It’s recognizable as a Pulsar from the front, but the added aggression—sharper lines, larger air intakes, more muscular tank shrouds—signals that this isn’t a bike to be taken lightly.
The tank is sculpted with knee recesses that actually work ergonomically. I’ve noticed many manufacturers design tanks that look great but offer poor grip during hard braking—the NS400’s tank shape allows you to lock your knees effectively, reducing arm fatigue during spirited riding.
The tail section is compact and upswept, giving the bike an aggressive rear profile. The split seat design looks sporty, though it does affect pillion comfort as we’ll discuss later. The underbelly exhaust is neatly integrated, keeping the center of gravity low and the visual lines clean.
Color options typically include red, black, and white variants, with graphics that are tasteful rather than overwhelming. Bajaj seems to have learned that their target buyer has matured—the teenager who wanted graphics plastered everywhere has grown up and wants something more refined.
Chassis and Handling: Built for Indian Roads
The NS400 uses a perimeter frame, which provides a good balance between rigidity and compliance. Compared to the Dominar’s more touring-oriented chassis, the NS400’s setup is tuned for agility and responsiveness.
The suspension setup consists of upside-down forks at the front and a monoshock at the rear. The USD forks are a significant upgrade over the telescopic units found on smaller Pulsars—they provide better feedback, resist diving under braking, and look considerably more premium.
The rear monoshock is preload-adjustable, allowing you to set sag based on your weight and whether you’re carrying a pillion. This adjustability is genuinely useful—riding solo versus with a passenger and luggage makes a significant difference in how the bike handles.
Wheelbase is slightly shorter than the Dominar, contributing to quicker steering response. In practice, the NS400 feels nimble for a 400cc bike. It changes direction with minimal effort, making it well-suited for the kind of riding most Indian enthusiasts do—navigating traffic during the week and attacking mountain roads on weekends.
The 17-inch wheels front and rear wear reasonably wide rubber. The grip levels are adequate for road riding in dry conditions, though enthusiastic riders might want to upgrade to stickier aftermarket tyres for dedicated spirited riding or track days.
Ground clearance is sufficient for typical Indian road hazards. Speed breakers and minor potholes don’t cause clearance anxiety, which is an important practical consideration that some manufacturers overlook when chasing low-slung aesthetics.
Braking: Confidence When It Matters
Braking duties are handled by a disc setup front and rear, with dual-channel ABS as standard. The front disc is generously sized, providing strong stopping power with good feel at the lever.
The ABS calibration deserves mention. Bajaj has tuned it to intervene relatively late, allowing experienced riders to explore the limits of traction before the system cuts in. For novice riders, this might feel less reassuring than an earlier-intervening system, but it preserves more of the riding experience for those who develop their skills.
The rear brake is adequate rather than exceptional. It provides the necessary stopping force but lacks the feel and modulation of the front. This is common in motorcycles at this price point and isn’t a significant limitation once you adjust your braking habits to rely more on the front.
Comfort and Ergonomics: The Daily Reality
Here’s where the NS400’s positioning as a street fighter becomes both its strength and its limitation.
The riding position is upright with a slight forward lean. The handlebars are set at a comfortable height for city riding—you’re not hunched over like on a dedicated sport bike, but you’re not sitting bolt upright like on a cruiser either. The footpegs are moderately rear-set, which looks sporty but doesn’t cramp your knees excessively.
The rider’s seat is firm but reasonably shaped. For daily commuting of 30-40 kilometers, it’s perfectly adequate. For longer rides beyond 100 kilometers, you’ll want to take breaks. The seat height is accessible for most Indian riders—I’m 5’9″ and can flatfoot comfortably at stops.
Pillion accommodation is a compromise. The rear seat is narrow, the grab rails are positioned for style rather than optimal ergonomics, and the suspension firmness transmits more impact to the rear seat than the front. If you regularly carry a pillion for longer rides, this is worth considering seriously.
Wind protection is minimal, as expected from a naked bike. At highway speeds above 100 kmph, windblast is significant and becomes tiring over extended riding. Aftermarket windscreens are available but alter the bike’s visual character.

Technology and Features
The NS400 comes equipped with a digital instrument cluster that displays essential information clearly—speed, RPM, fuel level, trip meters, and gear position indicator. The display is readable in various lighting conditions, though direct sunlight can wash it out slightly.
LED lighting throughout provides good visibility and modern aesthetics. The headlamp throw is adequate for urban and suburban riding, though as with most bikes in this segment, it could benefit from more output for unlit rural roads.
Other notable features include a USB charging port for device charging, engine kill switch, and hazard lights. These might seem basic, but their inclusion as standard equipment shows Bajaj’s understanding of what riders actually use daily.
Fuel Efficiency and Running Costs
Let’s talk about the practical economics of owning a 400cc Pulsar. The NS400’s fuel efficiency varies significantly based on riding style and conditions.
In city riding with moderate traffic, expect around 25-28 kmpl. Highway cruising at steady speeds improves this to 30-35 kmpl. Aggressive riding drops efficiency to 22-25 kmpl. These numbers are realistic based on what similar-capacity Bajaj and KTM owners report.
At current fuel prices, that translates to a running cost of approximately ₹3.00-3.50 per kilometer in mixed conditions. It’s not cheap, but it’s reasonable for a 400cc motorcycle. For comparison, a KTM Duke 390 achieves similar efficiency, while the Royal Enfield Himalayan 450 is slightly better due to its more relaxed tuning.
Insurance premiums are higher than smaller Pulsars—expect ₹8,000-12,000 annually for comprehensive coverage depending on your location and age. Service costs are reasonable, with Bajaj’s extensive network ensuring accessibility even in smaller towns.
The Competition Landscape
The NS400 enters a competitive space. Let’s address the obvious comparisons.
KTM Duke 390: The KTM is sharper, more aggressive, and offers better performance on smooth roads. It’s also more expensive and has higher maintenance costs. The NS400 is more comfortable, more affordable, and better suited for riders who want performance without the KTM’s intensity.
Royal Enfield Himalayan 450: A completely different philosophy—the Himalayan is an adventure tourer designed for versatility and long-distance comfort. If your riding involves more exploration and less corner-carving, the Himalayan makes more sense.
BMW G 310 R: More expensive, with a premium badge but less outright performance. The NS400 offers significantly better value for money in terms of features and capability.
Bajaj Dominar 400: The sibling rivalry is interesting. The Dominar is more touring-oriented with better wind protection and comfort. The NS400 is sportier and more engaging for spirited riding. Choose based on your primary riding style.
Who Should Buy the NS400
The NS400 makes sense for specific buyer profiles. It’s ideal for riders stepping up from 200cc bikes who want more performance without jumping to 600cc+ machines. It works for young professionals who want a capable daily rider with weekend fun potential. It suits enthusiasts who appreciate performance but need to maintain reasonable running costs.
It’s less suitable for frequent long-distance touring without modifications, for riders who regularly carry pillions on longer trips, for those who prioritize fuel efficiency above all else, or for absolute beginners with no motorcycle experience.
Pricing and Value Proposition
The NS400 is positioned aggressively in terms of pricing, significantly undercutting the KTM Duke 390 while offering comparable performance. This value proposition is perhaps its strongest selling point—you’re getting 400cc of genuine performance capability at a price that doesn’t require financial gymnastics.
Bajaj’s extensive service network further enhances the value equation. Parts are readily available, service costs are reasonable, and even in smaller towns, you can find competent mechanics familiar with the platform.
The Bottom Line
The Bajaj Pulsar NS400 represents the natural evolution of India’s most iconic motorcycle brand. It proves that Indian manufacturers can build genuinely capable mid-capacity motorcycles without importing engineering from Europe. It’s not perfect—the seat could be more comfortable for touring, the pillion accommodation is compromised, and the wind protection is minimal. But within its intended purpose—providing accessible, engaging performance for Indian riding conditions—it delivers convincingly.
For the rider who wants to step beyond the 200cc segment without losing the Pulsar’s accessible character, the NS400 is a compelling choice. It carries the Pulsar legacy forward while genuinely pushing into territory that was once exclusively European. Whether that’s enough to justify the purchase depends entirely on what you want from a motorcycle. But if excitement, value, and practical performance are on your priority list, the NS400 deserves serious consideration.
