Yamaha Finn vs Yamaha MT-25

The Yamaha Finn (2025) and the Yamaha MT-25 (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 Yamaha Finn is a cub / underbone with 114 cc, unlisted power and 100 kg; the Yamaha MT-25 is a naked bike with 250 cc, 35.4 hp and 166 kg. Power-to-weight with the rider: no data versus 146.9 hp/ton.

In the simulation the Yamaha Finn covers 0-100 km/h (speedometer) in 27.76 s and the Yamaha MT-25 in 6.35 s; the Yamaha MT-25 is quicker by 21.41 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 18.5 m for the Yamaha Finn (without ABS) and 17.3 m for the Yamaha MT-25 (ABS unknown, class assumption: no ABS). The Yamaha MT-25 stops 1.2 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 93 km/h (estimated from power and drag) versus 147 km/h (derived (GPS ratio)).

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 Yamaha Finn and model-specific parameters calibrated against published road tests for the Yamaha MT-25. Missing manufacturer data (power, torque) 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.
