Yamaha Finn vs Yuki Hammer 125

The Yamaha Finn (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 Finn is a cub / underbone with 114 cc, unlisted power and 100 kg; the Yuki Hammer 125 is a naked bike with 124 cc, 9.1 hp and unlisted weight. Power-to-weight with the rider: no data versus 47.6 hp/ton.

0-100 km/h (speedometer): Yamaha Finn 27.76 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 18.5 m for the Yamaha Finn (without ABS) and 17.3 m for the Yuki Hammer 125 (ABS unknown, class assumption: no ABS). The Yuki Hammer 125 stops 1.2 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 93 km/h (estimated from power and drag) 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 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.
