Bajaj Pulsar NS125 Specifications

The Bajaj Pulsar NS125 is powered by a 124.4cc single-cylinder, liquid-cooled, SOHC fuel-injected BS6 engine producing 14.5 PS @ 9000 rpm and 11.5 Nm @ 7000 rpm, paired with a 5-speed gearbox. ARAI-certified mileage is 50.5 kmpl. The liquid-cooled architecture - unique in the 125cc segment - uses a coolant circuit and radiator to regulate engine temperature, preventing the heat build-up that air-cooled 125cc rivals experience in stop-start city traffic.

Front suspension is telescopic forks. Rear suspension is a monoshock - a single gas-charged absorber providing more consistent damping than conventional twin-shock commuter setups. Kerb weight is 139 kg. Seat height is 800 mm. Fuel tank capacity is 12 litres. Ground clearance is approximately 165 mm.

Top speed is approximately 110-115 kmph under standard conditions.

Braking is a 300mm front disc with single-channel ABS and a rear drum brake. The single-channel ABS manages the front wheel during emergency braking. The NS125 runs on 17-inch alloy wheels with 100/80-17 front and 130/70-17 rear tyres. The instrument cluster is fully digital. The headlamp is the NS-series twin-pod LED unit.

Frequently Asked Questions

QWhat engine does the Bajaj Pulsar NS125 use?
The Bajaj Pulsar NS125 uses a 124.4cc single-cylinder, liquid-cooled, SOHC fuel-injected BS6 engine producing 14.5 PS @ 9000 rpm and 11.5 Nm @ 7000 rpm, paired with a 5-speed gearbox.
QWhy does the Pulsar NS125 have a liquid-cooled engine?
The NS125's liquid-cooled engine was the first in the Indian 125cc segment. Liquid cooling uses a coolant circuit and radiator to actively regulate engine temperature, keeping it consistent even during prolonged idling in traffic. Air-cooled engines rely on airflow over fins - at traffic signals, airflow stops and the engine heats up, radiating heat onto the rider. The liquid-cooled NS125 eliminates this in city conditions.
QWhat suspension does the Bajaj Pulsar NS125 have?
The Bajaj Pulsar NS125 has telescopic forks at the front and a rear monoshock. The monoshock provides single-point damping that handles road undulations more consistently than the twin-shock setups found on most commuter 125cc bikes at lower price points.
QWhat brakes does the Bajaj Pulsar NS125 have?
The Bajaj Pulsar NS125 has a 300mm front disc with single-channel ABS and a rear drum brake. The ABS prevents front-wheel lockup during emergency braking. The rear drum is functional for the 125cc performance level the bike operates at.
QWhat is the fuel tank capacity of Bajaj Pulsar NS125?
The Bajaj Pulsar NS125 has a 12-litre fuel tank. At real-world mileage of 44-48 kmpl, range per fill is approximately 530-580 km - adequate for most urban commute patterns and short weekend rides.
