Kawasaki Z900 vs Yamaha Exciter 155 VVA TCS

The Kawasaki Z900 (2025) and the Yamaha Exciter 155 VVA TCS (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 Kawasaki Z900 is a naked bike with 948 cc, 122.0 hp and 213 kg; the Yamaha Exciter 155 VVA TCS is a cub / underbone with 155 cc, 18.2 hp and 124 kg. Power-to-weight with the rider: 423.7 hp/ton versus 91.7 hp/ton. On this measure the Kawasaki Z900 is 362% ahead.

In the simulation the Kawasaki Z900 covers 0-100 km/h (speedometer) in 3.13 s and the Yamaha Exciter 155 VVA TCS in 10.46 s; the Kawasaki Z900 is quicker by 7.33 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 43.7 m for the Kawasaki Z900 (with ABS) and 46.8 m for the Yamaha Exciter 155 VVA TCS (with ABS). The Kawasaki Z900 stops 3.1 m shorter. Calculated top speed: 234 km/h (manufacturer claim) versus 115 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 Exciter 155 VVA TCS.
