Kawasaki Z900 vs TVS Jupiter 125

The Kawasaki Z900 (2025) and the TVS Jupiter 125 (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 Kawasaki Z900 is a naked bike with 948 cc, 122.0 hp and 213 kg; the TVS Jupiter 125 is a scooter with 125 cc, 8.1 hp and unlisted weight. Power-to-weight with the rider: 423.7 hp/ton versus 40.8 hp/ton. On this measure the Kawasaki Z900 is 940% ahead.

In the simulation the Kawasaki Z900 covers 0-100 km/h (speedometer) in 3.13 s and the TVS Jupiter 125 in 38.88 s; the Kawasaki Z900 is quicker by 35.75 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 15.7 m for the Kawasaki Z900 (with ABS) and 17.9 m for the TVS Jupiter 125 (ABS unknown, class assumption: no ABS). The Kawasaki Z900 stops 2.2 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 234 km/h (manufacturer claim) versus 91 km/h (manufacturer claim).

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 both. Missing manufacturer data (weight) is estimated by class regression, not measured. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.
