RKS Neon125 vs Yamaha NMAX 125

The RKS Neon125 (2026) and the Yamaha NMAX 125 (2025) 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 RKS Neon125 is a scooter with 125 cc, 9.3 hp and unlisted weight; the Yamaha NMAX 125 is a scooter with 125 cc, 12.1 hp and 132 kg. Power-to-weight with the rider: 49.5 hp/ton versus 58.3 hp/ton. On this measure the Yamaha NMAX 125 is 18% ahead.

0-100 km/h (speedometer): RKS Neon125 not reached (top simulated speed 84 km/h), Yamaha NMAX 125 20.34 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.9 m for the RKS Neon125 (ABS unknown, class assumption: no ABS) and 17.9 m for the Yamaha NMAX 125 (ABS unknown, class assumption: no ABS). The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 84 km/h (estimated from power and drag) versus 99 km/h (GPS measurement).

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 the RKS Neon125 and model-specific parameters calibrated against published road tests for the Yamaha NMAX 125.
