Honda CRF250 Rally vs RKS RZ125

The Honda CRF250 Rally (2026) 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 CRF250 Rally is a enduro bike with 249 cc, 24.1 hp and 153 kg; the RKS RZ125 is a sport bike with 125 cc, 14.5 hp and unlisted weight. Power-to-weight with the rider: 105.9 hp/ton versus 63.8 hp/ton. On this measure the Honda CRF250 Rally is 66% ahead.

In the simulation the Honda CRF250 Rally covers 0-100 km/h (speedometer) in 7.61 s and the RKS RZ125 in 13.42 s; the Honda CRF250 Rally is quicker by 5.80 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 46.8 m for the Honda CRF250 Rally (with ABS) and 36.4 m for the RKS RZ125 (with ABS). The RKS RZ125 stops 10.4 m shorter. Calculated top speed: 123 km/h (estimated from power and drag) 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 class-average calibration (no accepted model-specific road test) for both.
