Kawasaki Z900 vs Yamaha Tracer 9
ESTIMATED SIMULATION
Run the comparison →The Kawasaki Z900 (2025) and the Yamaha Tracer 9 (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 Tracer 9 is a touring bike with 890 cc, 117.3 hp and 219 kg. Power-to-weight with the rider: 423.7 hp/ton versus 399.1 hp/ton. On this measure the Kawasaki Z900 is 6% ahead.
In the simulation the Kawasaki Z900 covers 0-100 km/h (speedometer) in 3.13 s and the Yamaha Tracer 9 in 2.95 s; the Yamaha Tracer 9 is quicker by 0.18 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 45.0 m for the Yamaha Tracer 9 (ABS unknown, class assumption: no ABS). The Kawasaki Z900 stops 1.3 m shorter. Calculated top speed: 234 km/h (manufacturer claim) versus 215 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 both. 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.
