Source: https://indianautoforum.com/bikes/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.

## FAQs

**What 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.

**Why 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.

**What 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.

**What 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.

**What 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.
