Both bikes wear aggressive streetfighter styling, both promise thrilling performance for their price, and both have loyal fan followings — but they are built for slightly different riders.

In this detailed 2026 comparison, we break down the price, engine performance, mileage, features, braking, ride quality, and overall value for money of the KTM Duke 250 and Bajaj Pulsar NS400Z, so you can decide which one deserves your garage.

Quick Verdict (TL;DR)

• Choose the KTM Duke 250 if you want a lighter, more agile bike with premium European build quality, a slightly more refined ride, and don’t mind paying more for the KTM badge.
• Choose the Bajaj Pulsar NS400Z if you want more outright power, a bigger 349cc engine, a heavier road presence, and significantly better value for money at a lower price point.

Let’s get into the details.

KTM Duke 250 vs Bajaj Pulsar NS400Z: Price Comparison

Bike	Ex-Showroom Price (approx.)	On-Road Price (Delhi, approx.)
KTM Duke 250	₹2.21 – 2.39 lakh	₹2.50 – 2.60 lakh
Bajaj Pulsar NS400Z	₹1.80 – 1.86 lakh	₹1.99 – 2.20 lakh

This is the single biggest differentiator between the two bikes. The Pulsar NS400Z undercuts the Duke 250 by roughly ₹40,000–50,000 on-road, despite offering a larger engine and more power on paper. If budget is a primary concern, the NS400Z has a clear head start before you even look at specs.

Engine, Power & Performance

Specification	KTM Duke 250	Bajaj Pulsar NS400Z
Engine Displacement	249.07cc, single-cylinder, liquid-cooled	349.13cc, single-cylinder, liquid-cooled, DOHC
Max Power	~31 PS @ 9,000 rpm	~40–43 PS @ 9,000 rpm
Max Torque	25 Nm	33.2 Nm @ 7,500 rpm
Gearbox	6-speed with slipper clutch	6-speed with slipper clutch
Claimed Top Speed	~148 kmph	~150–157 kmph
Quickshifter	Quickshifter+ (standard)	SportShift bi-directional quickshifter

n paper, the Pulsar NS400Z is the clear power leader, producing noticeably more horsepower and a healthier mid-range torque spread thanks to its larger 349cc engine. This translates into stronger overtakes and more effortless highway cruising.

The KTM Duke 250, while down on outright numbers, is known for a refined, linear power delivery. It doesn’t have the same brute force, but the engine feels eager and responsive throughout the rev range, and the bike’s lighter weight helps it never feel underpowered in city riding.

If your priority is outright performance and triple-digit highway speeds, the NS400Z wins comfortably. If you want a smooth, confidence-inspiring engine for daily use, the Duke 250 still holds its own.

Mileage & Fuel Efficiency

Bike	ARAI/Claimed Mileage	Fuel Tank Capacity
KTM Duke 250	~30 kmpl	15 litres
Bajaj Pulsar NS400Z	~28 kmpl	12 litres

The Duke 250 has a slight edge in fuel efficiency and also carries a larger 15-litre tank, giving it a longer real-world riding range compared to the NS400Z’s 12-litre tank. For riders who commute daily or ride long distances between fuel stops, this is a meaningful practical advantage in the KTM’s favour.

Weight, Handling & Chassis

Specification	KTM Duke 250	Bajaj Pulsar NS400Z
Kerb Weight	~163–169 kg	~176 kg
Front Suspension	WP Apex USD forks	43mm USD forks
Rear Suspension	WP monoshock	Monoshock with Nitrox, adjustable
Frame	Trellis frame	Perimeter frame

The KTM Duke 250 is noticeably lighter, which makes it feel flickable and easy to manage in city traffic, tight corners, and stop-and-go commutes. Its trellis frame and WP suspension setup are widely regarded as some of the best in this segment for outright handling precision.

The Pulsar NS400Z is heavier, but this added mass — combined with its perimeter frame — gives it a more planted, stable feel at higher speeds and on the highway. It’s less flickable than the Duke but rewards riders with confidence during fast, sweeping corners.

Braking & Safety Features

Feature	KTM Duke 250	Bajaj Pulsar NS400Z
ABS	Dual-channel Supermoto ABS	Dual-channel ABS
Traction Control	Not available	Available
Riding Modes	Limited/single mode	Up to 4 riding modes
Slipper Clutch	Yes	Yes

The Pulsar NS400Z pulls ahead here with traction control and multiple riding modes, features typically found on more premium motorcycles. This gives riders more control over power delivery in different conditions — a genuine advantage for less experienced riders or those riding in the rain

Features & Instrument Cluster

Both motorcycles come loaded with modern features expected from a 2026 streetfighter:

KTM Duke 250:

• 5-inch full-colour TFT instrument cluster
• LED headlamp and tail lamp
• Ride-by-wire throttle
• Bluetooth connectivity via KTM app

Bajaj Pulsar NS400Z:

• Fully digital LCD cluster with dot-matrix display
• Bluetooth connectivity via Bajaj Ride Connect app
• LED projector headlamp with signature DRL
• Lap timer and navigation support via app

Feature-for-feature, the two are fairly closely matched, though the Duke’s TFT display is generally considered sharper and more premium in feel.

Design & Styling

The KTM Duke 250 carries KTM’s signature “Ready to Race” design language — sharp edges, a compact tank, and an aggressive minimalist stance inherited from its bigger sibling, the 390 Duke.

The Bajaj Pulsar NS400Z takes a bolder, more muscular approach with fighter-jet-inspired panels, a wider stance, a signature Lightning Bolt DRL, and carbon-fibre-style accents. It looks and feels like a larger, more dominant motorcycle on the road.

Styling is subjective, but the NS400Z generally gives more “big bike” road presence for the price, while the Duke 250 leans into a sportier, more compact aesthetic.
