Honda CB125F vs RKS Neon125

The Honda CB125F (2025) and the RKS Neon125 (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 CB125F is a naked bike with 124 cc, 10.7 hp and 117 kg; the RKS Neon125 is a scooter with 125 cc, 9.3 hp and unlisted weight. Power-to-weight with the rider: 55.9 hp/ton versus 49.5 hp/ton. On this measure the Honda CB125F is 13% ahead.

0-100 km/h (speedometer): Honda CB125F 21.61 s, RKS Neon125 not reached (top simulated speed 84 km/h). In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.3 m for the Honda CB125F (ABS unknown, class assumption: no ABS) and 17.9 m for the RKS Neon125 (ABS unknown, class assumption: no ABS). The Honda CB125F stops 0.6 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 100 km/h (manufacturer claim) versus 84 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 CB125F and class-average calibration (no accepted model-specific road test) for the RKS Neon125.
