Bajaj NS 400Z 350cc launched in India with minor engine tweaks - Here’s what’s new

Following suit with Triumph and KTM, Bajaj has reworked the larger-capacity engine in the NS 400Z to fit within the new GST 2.0 norms. The downsized NS will now have a slightly tweaked engine with a revised power and torque figure.

Downsized but familiar

The styling, feature list, and hardware of the new bike remain exactly the same. The only update lies in the engine. The NS 400Z now uses a 349.13 cc liquid-cooled single-cylinder engine, shared with the revised Dominar 400. The motor now produces 40.6 PS at 9,000 rpm and 33.2 Nm at 7,500 rpm. The new changes bring a power dip of about 2.4 PS and a torque dip of around 1.8 Nm.

Bajaj has now opted for a shorter stroke, while the bore is still 89 mm. The stroke has been slightly reduced from 60 mm to 56.1 mm. The bike sits in line with its Triumph and KTM counterparts, which have also received such downsizing treatment.

The NS 400Z continues to be listed at Rs 1,93,900, unchanged despite the shift to a smaller engine. Since the bike is already aptly priced, its possible it would not see a price drop, unlike the Dominar 400.

Before NS400Z, Triumph had launched the 350cc version of the Triumph Speed 400. The lineup included the Triumph Speed 400, Triumph Scrambler 400X, Triumph Scrambler 400 XC, and Triumph Thruxton 400. And just recently KTM has also revised the pricing and engine specs of some of their bikes.

The revised GST rules for two-wheelers 2025 states that bikes and scooters up to 350cc will now attract just 18% GST. Premium motorcycles above 350cc will now face a steep hike in GST, rising to 40% from the former 31%. These new prices make the bikes even more expensive for Indian buyers.

At the same time, electric two-wheelers will only attract 5% GST, supporting the government’s aim to shift toward greener mobility.
