Following the arrival of the updated Dominar series, Bajaj Auto has upgraded its most powerful Pulsar with more than just a bump in performance. The NS400Z UG has arrived in the market at an ex-showroom, Delhi price of Rs 1.92 lakh, featuring sharper throttle behaviour, quicker acceleration times, hardware upgrades and added electronic systems with a price bump of just over Rs. 7,000. Power from the 373 cc single-cylinder liquid-cooled engine has increased from 40 PS to 43 PS with the peak arriving at 9,000 rpm. While the torque output remains at 35 Nm, it now peaks slightly higher in the rev band at 7,500 rpm. Bajaj has lifted the redline to 10,700 rpm in Sport mode, 1,000 rpm higher than before while Road, Off-road and Rain modes cap out at 10,300 rpm. As a result, the 0 to 60 kmph time has improved from 3.2 seconds to 2.7 seconds and the sprint to 100 kmph now takes 6.4 seconds, down from 7.5 seconds. The overall top speed has gone up from 150 kmph to 157 kmph as well while the fuel economy figures continue to stay the same at 28 kmpl according to the brand despite the performance increments.

The new Bajaj Pulsar NS400 Z UG now features a wider 150 section steel radial tyre at the rear and replaces the front bias-ply with a radial unit for better grip and ride feel. The braking system uses sintered pads up front, resulting in stopping distances shorter by up to 7 per cent. Bajaj’s proprietary Sport Shift system (bi-directional quickshifter) which enables clutchless full-throttle gearshifts in both directions has been introduced as part of the update. Amidst these upgrades, the chassis remains unchanged with the same twin-spar steel perimeter frame and the motorcycle’s kerb weight stands identical at 174 kg. It runs on 17-inch wheels with 110/70 front and 150/60 rear tyre sizes. Suspension travel remains at 120 mm at the front and 130 mm at the rear. Seat height is set at 805 mm, ground clearance at 165 mm and the fuel tank holds 12 litres for the naked machine.

It returns a power-to-weight ratio of 247 PS per ton. Considering the price, the updated NS400 Z UG is a bang for buck on paper and it also undercuts rivals such as Hero Mavrick 440, TVS Apache RTR 310, etc in terms of performance big time.
