Engineered by Bajaj for the scooter motorcycle segment, the 2006 Bajaj Chetak utilizes a 145.5 cc (8.9 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 7.5 HP (5.5 kW) at 5,500 rpm while maximum torque reaches 10.8 Nm (8 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 51.5 HP per liter and a 2,000 rpm working window between peak torque (3,500 rpm) and peak power (5,500 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Chetak measures 103 kg (227 lbs) wet (curb), translating to a power-to-weight ratio of 0.07 HP/kg (13.73 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,230 mm (48.4 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
