Honda Africa Twin vs Yamaha Sirius FI

The Honda Africa Twin (2025) and the Yamaha Sirius FI (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 Sirius FI is a cub / underbone with 114 cc, 8.6 hp and 98 kg. Power-to-weight with the rider: 315.3 hp/ton versus 49.6 hp/ton. On this measure the Honda Africa Twin is 536% ahead.

0-100 km/h (speedometer): Honda Africa Twin 3.02 s, Yamaha Sirius FI not reached (top simulated speed 89 km/h). In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 14.9 m for the Honda Africa Twin (with ABS) and 18.5 m for the Yamaha Sirius FI (ABS unknown, class assumption: no ABS). The Honda Africa Twin stops 3.6 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 199 km/h (manufacturer claim) versus 88 km/h (estimated from power and drag).

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 the Honda Africa Twin and class-average calibration (no accepted model-specific road test) for the Yamaha Sirius FI.
