Honda Activa 125 vs Yamaha PG-1

The Honda Activa 125 (2025) and the Yamaha PG-1 (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 Honda Activa 125 is a scooter with 124 cc, 8.3 hp and 107 kg; the Yamaha PG-1 is a cub / underbone with 114 cc, unlisted power and 109 kg. Power-to-weight with the rider: 45.7 hp/ton versus no data.

In the simulation the Honda Activa 125 covers 0-100 km/h (speedometer) in 36.16 s and the Yamaha PG-1 in 29.82 s; the Yamaha PG-1 is quicker by 6.34 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.9 m for the Honda Activa 125 (ABS unknown, class assumption: no ABS) and 16.9 m for the Yamaha PG-1 (with ABS). The Yamaha PG-1 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: 90 km/h (manufacturer claim) versus 93 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 Activa 125 and class-average calibration (no accepted model-specific road test) for the Yamaha PG-1. 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.
