Engineered by Tvs for the scooter motorcycle segment, the 2022 Tvs Jupiter 125 pairs a 124.8 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 8.1 HP (5.9 kW) at 6,500 rpm while maximum torque reaches 10.5 Nm (7.7 lb-ft) at 4,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 64.9 HP per liter and a 2,000 rpm working window between peak torque (4,500 rpm) and peak power (6,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Jupiter 125 measures 108 kg (238 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (13.33 kg per horsepower). Rider ergonomics and chassis geometry center around a 765 mm (30.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,275 mm (50.2 in) wheelbase engineered for quick, flickable steering geometry. The 5.1-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
