Honda Africa Twin vs RKS RZ125

The Honda Africa Twin (2025) and the RKS RZ125 (2026) 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 RKS RZ125 is a sport bike with 125 cc, 14.5 hp and unlisted weight. Power-to-weight with the rider: 315.3 hp/ton versus 63.8 hp/ton. On this measure the Honda Africa Twin is 394% ahead.

In the simulation the Honda Africa Twin covers 0-100 km/h (speedometer) in 3.02 s and the RKS RZ125 in 13.42 s; the Honda Africa Twin is quicker by 10.40 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 36.4 m for the RKS RZ125 (with ABS). The RKS RZ125 stops 5.0 m shorter. Calculated top speed: 199 km/h (manufacturer claim) versus 125 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 RKS RZ125.
