Yamaha NMAX 125 vs Yuki Hammer 125
ESTIMATED SIMULATION
Run the comparison →The Yamaha NMAX 125 (2025) and the Yuki Hammer 125 (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 Yamaha NMAX 125 is a scooter with 125 cc, 12.1 hp and 132 kg; the Yuki Hammer 125 is a naked bike with 124 cc, 9.1 hp and unlisted weight. Power-to-weight with the rider: 58.3 hp/ton versus 47.6 hp/ton. On this measure the Yamaha NMAX 125 is 22% ahead.
0-100 km/h (speedometer): Yamaha NMAX 125 20.34 s, Yuki Hammer 125 not reached (top simulated speed 69 km/h). In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.9 m for the Yamaha NMAX 125 (ABS unknown, class assumption: no ABS) and 17.3 m for the Yuki Hammer 125 (ABS unknown, class assumption: no ABS). The Yuki Hammer 125 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: 99 km/h (GPS measurement) versus 83 km/h (manufacturer claim).
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 Yamaha NMAX 125 and class-average calibration (no accepted model-specific road test) for the Yuki Hammer 125. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.

Data sources and calibration
Specifications: the sources below (manufacturer pages, plus road-test or spec sites where the manufacturer gives no figure). Acceleration, braking and top speed: Moto Kıyas physics simulation (power/torque curve, gearing, drag, traction and wheelie limits, ABS assumption), calibrated against published road tests where available. Estimated, not measured.
