Mondial Fuzion 125 vs Yamaha R25

The Mondial Fuzion 125 (2026) and the Yamaha R25 (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 Mondial Fuzion 125 is a scooter with 124 cc, 9.1 hp and unlisted weight; the Yamaha R25 is a sport bike with 250 cc, 35.4 hp and 169 kg. Power-to-weight with the rider: 46.3 hp/ton versus 145.1 hp/ton. On this measure the Yamaha R25 is 214% ahead.

0-100 km/h (speedometer): Mondial Fuzion 125 not reached (top simulated speed 69 km/h), Yamaha R25 6.40 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.9 m for the Mondial Fuzion 125 (ABS unknown, class assumption: no ABS) and 14.4 m for the Yamaha R25 (ABS unknown, class assumption: no ABS). The Yamaha R25 stops 3.5 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 80 km/h (manufacturer claim) versus 158 km/h (GPS measurement).

All values are an estimated simulation, not road-test measurements. Technical data comes from the sources listed below; the model uses class-average calibration (no accepted model-specific road test) for the Mondial Fuzion 125 and model-specific parameters calibrated against published road tests for the Yamaha R25. 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.
