Kawasaki Vulcan S vs Yamaha MT-09

The Kawasaki Vulcan S (2026) and the Yamaha MT-09 (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 Vulcan S is a cruiser with 649 cc, 59.9 hp and unlisted weight; the Yamaha MT-09 is a naked bike with 890 cc, 117.3 hp and 193 kg. Power-to-weight with the rider: 226.5 hp/ton versus 437.8 hp/ton. On this measure the Yamaha MT-09 is 93% ahead.

In the simulation the Kawasaki Vulcan S covers 0-100 km/h (speedometer) in 4.49 s and the Yamaha MT-09 in 3.11 s; the Yamaha MT-09 is quicker by 1.38 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 44.7 m for the Kawasaki Vulcan S (with ABS) and 48.0 m for the Yamaha MT-09 (ABS unknown, class assumption: no ABS). The Kawasaki Vulcan S stops 3.3 m shorter. Calculated top speed: 173 km/h (estimated from power and drag) versus 199 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 model-specific parameters calibrated against published road tests for both. Missing manufacturer data (weight) 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.
