Bajaj has given its flagship streetfighter, the Pulsar NS400Z, a fresh boost for 2025. If you’re eyeing this bike, here’s exactly what’s changed and why these updates make it a sharper ride than before.
More Power Under The Tank
One of the biggest highlights is under the skin. The familiar 373cc single-cylinder, liquid-cooled engine gets an upgrade with a forged piston instead of the old cast one. This small change has pushed the power up by nearly 3bhp, taking the output to 42.4bhp. The redline is higher now too, which means more fun when you wring that throttle.
Torque stays the same at 35Nm, but the improved power helps the bike reach 0 to 100 kmph quicker and boosts the top speed to 157 kmph. It’s a neat upgrade for riders who love stretching their bike on open roads.
New Sport Shift For Sport Mode
Bajaj has thrown in a bi-directional quick shifter this time, which they call Sport Shift. It only works in the Sport riding mode. So if you’re blasting down a highway or carving corners, you can upshift and downshift quicker without pulling the clutch each time.
The bike now offers four modes — Sport, Road, Rain, and Off-road. The quick shifter is software-driven rather than the typical pressure sensor type. It’s a first for the Pulsar line and should make spirited rides more engaging.
Better Grip And Brakes
Bajaj didn’t stop at just the engine. They swapped out the older cross-ply MRF Rev Z tyres for stickier Apollo Alpha H1 radials. These tyres promise more grip and confidence, especially when leaning into corners or making quick stops.
Speaking of stopping, the front disc now uses sintered brake pads instead of the old organic ones. Riders can expect stronger bite and better braking feel. At the back, the tyre is now a chunkier 150-section, replacing the older 140. More rubber means better road contact and stability.
Sensible Price Bump
With all these tweaks, you’d expect a big price jump. But Bajaj has kept it in check. The 2025 Pulsar NS400Z now costs Rs. 1.92 lakh (ex-showroom). That’s just Rs. 7,000 more than before, which feels fair considering the new hardware and performance boost.
Should You Consider It?
If you’re hunting for a value-packed streetfighter with a bit more thrill than your everyday commuter, the updated NS400Z makes a strong case. More power, a slick quick shifter, stickier tyres, and better brakes — all without burning a hole in your wallet.
So next time you spot a Pulsar NS400Z cruising past, know this isn’t the same bike from last year. Bajaj has turned up the heat just enough to keep the NS400Z roaring ahead of the pack.
