Honda Dio 110 vs RKS RZ125

The Honda Dio 110 (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 Dio 110 is a scooter with 109 cc, 8.6 hp and 96 kg; the RKS RZ125 is a sport bike with 125 cc, 14.5 hp and unlisted weight. Power-to-weight with the rider: 50.2 hp/ton versus 63.8 hp/ton. On this measure the RKS RZ125 is 27% ahead.

0-100 km/h (speedometer): Honda Dio 110 not reached (top simulated speed 68 km/h), RKS RZ125 13.42 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.9 m for the Honda Dio 110 (ABS unknown, class assumption: no ABS) and 13.1 m for the RKS RZ125 (with ABS). The RKS RZ125 stops 4.8 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 84 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 Dio 110 and class-average calibration (no accepted model-specific road test) for the RKS RZ125.
