Yamaha R25 vs Yamaha XMAX 250

The Yamaha R25 (2025) and the Yamaha XMAX 250 (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 R25 is a sport bike with 250 cc, 35.4 hp and 169 kg; the Yamaha XMAX 250 is a scooter with 250 cc, 22.4 hp and 183 kg. Power-to-weight with the rider: 145.1 hp/ton versus 86.8 hp/ton. On this measure the Yamaha R25 is 67% ahead.

In the simulation the Yamaha R25 covers 0-100 km/h (speedometer) in 6.40 s and the Yamaha XMAX 250 in 11.65 s; the Yamaha R25 is quicker by 5.24 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 40.0 m for the Yamaha R25 (ABS unknown, class assumption: no ABS) and 45.2 m for the Yamaha XMAX 250 (with ABS). The Yamaha R25 stops 5.2 m shorter. Calculated top speed: 158 km/h (GPS measurement) versus 126 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 model-specific parameters calibrated against published road tests for both.
