Honda NC750X vs RKS RZ125

The Honda NC750X (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 NC750X is a adventure bike with 745 cc, 57.8 hp and 226 kg; the RKS RZ125 is a sport bike with 125 cc, 14.5 hp and unlisted weight. Power-to-weight with the rider: 192.0 hp/ton versus 63.8 hp/ton. On this measure the Honda NC750X is 201% ahead.

In the simulation the Honda NC750X covers 0-100 km/h (speedometer) in 4.49 s and the RKS RZ125 in 13.42 s; the Honda NC750X is quicker by 8.92 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 NC750X (with ABS) and 36.4 m for the RKS RZ125 (with ABS). The RKS RZ125 stops 5.0 m shorter. Calculated top speed: 163 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.
