Kawasaki Z900 vs Yamaha PG-1

The Kawasaki Z900 (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 Kawasaki Z900 is a naked bike with 948 cc, 122.0 hp and 213 kg; the Yamaha PG-1 is a cub / underbone with 114 cc, unlisted power and 109 kg. Power-to-weight with the rider: 423.7 hp/ton versus no data.

In the simulation the Kawasaki Z900 covers 0-100 km/h (speedometer) in 3.13 s and the Yamaha PG-1 in 29.82 s; the Kawasaki Z900 is quicker by 26.69 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 15.7 m for the Kawasaki Z900 (with ABS) and 16.9 m for the Yamaha PG-1 (with ABS). The Kawasaki Z900 stops 1.1 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 234 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 Kawasaki Z900 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.
