2025 Bajaj Pulsar NS400Z Launch: Bajaj’s biggest Pulsar just got bigger for 2025. More power, a quickshifter, and better bits all around – looks like they’ve been listening to what riders actually want.
More Muscle Under the Hood
The big news? That 373cc liquid-cooled single now makes 42.4 bhp instead of 39.5 bhp. That’s a solid 3 bhp jump that puts it right where the old KTM 390 Duke used to sit. Bajaj’s keeping quiet about torque numbers for now, but we’re betting it’ll climb from 35 Nm to somewhere around 37 Nm.
And honestly, this wasn’t just about flexing on spec sheets. With the Triumph Speed 400 and Royal Enfield Guerrilla 450 both hitting 40 bhp, the NS400Z needed this bump to stay relevant. Nobody wants to be the slowest kid in the playground, right?
Finally, a Quickshifter!
About time, really. The 2025 NS400Z is getting a quickshifter – something that should’ve been there from day one if you ask most riders. We’re not sure yet if it’s standard or you’ll have to pay extra for it. Knowing Bajaj’s approach to keeping prices sharp, it might be an optional extra.
For those scratching their heads – a quickshifter lets you shift up without touching the clutch. Perfect for when you’re having a proper go and don’t want to break your rhythm. It’s one of those things that sounds fancy but actually makes a real difference on the road.

Better Stopping Power and Grip
Here’s where Bajaj tackled some genuine complaints. Those organic brake pads? Gone. The 2025 model gets sintered pads that should bite harder and fade less when you’re really leaning on them. At 174 kg, this bike needs all the stopping power it can get.
The tyres got an upgrade too. Those MRF units have made way for Apollo Alpha H1 rubber, and the rear’s grown from 140 to 150 section. Anyone who’s pushed the original hard will tell you the tyres were… well, let’s just say they weren’t the bike’s strongest suit. This should fix that.
What Hasn’t Changed (And That’s Fine)
The good stuff stays put. You still get that aggressive streetfighter look with those cool Z-shaped LED DRLs and the floating panel design that makes it look more expensive than it is. The 807mm seat height means most riders won’t need a stepladder to get on.
All the tech goodies are still there – four ride modes, traction control you can switch off, dual-channel ABS, and that colour screen with Bluetooth. The 12-litre tank and 6-speed box with the slip-assist clutch carry over too, along with those 43mm USD forks and the adjustable rear shock.
What’ll It Cost You?
Here’s the million-rupee question. The current bike costs ₹1.85 lakh ex-showroom, making it the cheapest way to get 40+ bhp. Word is the 2025 model will cost about ₹10,000 more, which still keeps it well under ₹2 lakh.
Even with the hike, it’s still way cheaper than a KTM 390 Duke at ₹3.15 lakh or the Triumph Speed 400 at ₹2.33 lakh. The bikes are already hitting showrooms, and deliveries should start in the first week of June.
The Real Talk
Look, the 2025 NS400Z fixes most of what was wrong with the original while keeping what made it special – that killer price-to-performance ratio. More power, better brakes, stickier tyres, and a quickshifter. It’s exactly the kind of update that shows Bajaj actually rides their own bikes.
Will it feel as polished as a KTM? Nope. As refined as a Triumph? Not even close. But here’s the thing – at this price, it doesn’t need to. If you want proper 400cc thrills without selling a kidney, the updated NS400Z just became an even better deal.
For most riders, that extra refinement isn’t worth paying nearly double. Sometimes, good enough really is good enough.
