TVS Jupiter 125 vs Yamaha Finn

The TVS Jupiter 125 (2025) and the Yamaha Finn (2025) are compared with the same Moto Kıyas physics model under identical conditions: flat dry asphalt, no wind, a 75 kg rider and no passenger. The TVS Jupiter 125 is a scooter with 125 cc, 8.1 hp and unlisted weight; the Yamaha Finn is a cub / underbone with 114 cc, unlisted power and 100 kg. Power-to-weight with the rider: 40.8 hp/ton versus no data.

In the simulation the TVS Jupiter 125 covers 0-100 km/h (speedometer) in 38.88 s and the Yamaha Finn in 27.76 s; the Yamaha Finn is quicker by 11.12 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.9 m for the TVS Jupiter 125 (ABS unknown, class assumption: no ABS) and 18.5 m for the Yamaha Finn (without ABS). The TVS Jupiter 125 stops 0.6 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 91 km/h (manufacturer claim) versus 93 km/h (estimated from power and drag).

All values are an estimated simulation, not road-test measurements. Technical data comes from the sources listed below; the model uses model-specific parameters calibrated against published road tests for the TVS Jupiter 125 and class-average calibration (no accepted model-specific road test) for the Yamaha Finn. Missing manufacturer data (weight) is estimated by class regression, not measured. Missing manufacturer data (power, torque) is estimated by class regression, not measured.
