Engineered by Bajaj for the sport motorcycle segment, the 2025 Bajaj Pulsar NS125 relies on a 124.5 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, maximum torque reaches 11 Nm (8.1 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive.
On the scales, the Pulsar NS125 measures 144 kg (317 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,353 mm (53.3 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
