Kawasaki Vulcan S vs Suzuki GSX-S1000GT

The Kawasaki Vulcan S (2026) and the Suzuki GSX-S1000GT (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 Suzuki GSX-S1000GT is a touring bike with 999 cc, 150.2 hp and unlisted weight. Power-to-weight with the rider: 226.5 hp/ton versus 485.4 hp/ton. On this measure the Suzuki GSX-S1000GT is 114% ahead.

In the simulation the Kawasaki Vulcan S covers 0-100 km/h (speedometer) in 4.49 s and the Suzuki GSX-S1000GT in 2.91 s; the Suzuki GSX-S1000GT is quicker by 1.57 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 45.0 m for the Suzuki GSX-S1000GT (ABS unknown, class assumption: no ABS). The Kawasaki Vulcan S stops 0.3 m shorter. Calculated top speed: 173 km/h (estimated from power and drag) versus 240 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. Missing manufacturer data (weight) is estimated by class regression, not measured. Missing manufacturer data (weight) is estimated by class regression, not measured.
