Yamaha MT-09 vs Yamaha R25

The Yamaha MT-09 (2025) 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 Yamaha MT-09 is a naked bike with 890 cc, 117.3 hp and 193 kg; the Yamaha R25 is a sport bike with 250 cc, 35.4 hp and 169 kg. Power-to-weight with the rider: 437.8 hp/ton versus 145.1 hp/ton. On this measure the Yamaha MT-09 is 202% ahead.

In the simulation the Yamaha MT-09 covers 0-100 km/h (speedometer) in 3.11 s and the Yamaha R25 in 6.40 s; the Yamaha MT-09 is quicker by 3.29 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 48.0 m for the Yamaha MT-09 (ABS unknown, class assumption: no ABS) and 40.0 m for the Yamaha R25 (ABS unknown, class assumption: no ABS). The Yamaha R25 stops 8.0 m shorter. Calculated top speed: 199 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 model-specific parameters calibrated against published road tests for both.
