Honda NX500 vs Yamaha R25

The Honda NX500 (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 Honda NX500 is a adventure bike with 471 cc, 46.9 hp and 196 kg; the Yamaha R25 is a sport bike with 250 cc, 35.4 hp and 169 kg. Power-to-weight with the rider: 173.2 hp/ton versus 145.1 hp/ton. On this measure the Honda NX500 is 19% ahead.

In the simulation the Honda NX500 covers 0-100 km/h (speedometer) in 5.11 s and the Yamaha R25 in 6.40 s; the Honda NX500 is quicker by 1.29 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 41.4 m for the Honda NX500 (with ABS) and 40.0 m for the Yamaha R25 (ABS unknown, class assumption: no ABS). The Yamaha R25 stops 1.4 m shorter. Calculated top speed: 152 km/h (estimated from power and drag) 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 Honda NX500 and model-specific parameters calibrated against published road tests for the Yamaha R25.
