RKS Neon125 vs Suzuki DR-Z4S

The RKS Neon125 (2026) and the Suzuki DR-Z4S (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 Suzuki DR-Z4S is a enduro bike with 398 cc, unlisted power and 151 kg. Power-to-weight with the rider: 49.5 hp/ton versus no data.

0-100 km/h (speedometer): RKS Neon125 not reached (top simulated speed 84 km/h), Suzuki DR-Z4S 4.98 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 16.9 m for the Suzuki DR-Z4S (with ABS). The Suzuki DR-Z4S stops 1.0 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 (estimated from power and drag) versus 145 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. Missing manufacturer data (power, torque) is estimated by class regression, not measured. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.
