Honda Africa Twin vs Yamaha R25

The Honda Africa Twin (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 Africa Twin is a adventure bike with 1,084 cc, 100.6 hp and 244 kg; the Yamaha R25 is a sport bike with 250 cc, 35.4 hp and 169 kg. Power-to-weight with the rider: 315.3 hp/ton versus 145.1 hp/ton. On this measure the Honda Africa Twin is 117% ahead.

In the simulation the Honda Africa Twin covers 0-100 km/h (speedometer) in 3.02 s and the Yamaha R25 in 6.40 s; the Honda Africa Twin is quicker by 3.38 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 Africa Twin (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: 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.
