BMW R 1300 GS vs Kawasaki Vulcan S

The BMW R 1300 GS (2024) and the Kawasaki Vulcan S (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 BMW R 1300 GS is a adventure bike with 1,300 cc, 143.5 hp and 237 kg; the Kawasaki Vulcan S is a cruiser with 649 cc, 59.9 hp and unlisted weight. Power-to-weight with the rider: 459.9 hp/ton versus 226.5 hp/ton. On this measure the BMW R 1300 GS is 103% ahead.

In the simulation the BMW R 1300 GS covers 0-100 km/h (speedometer) in 2.96 s and the Kawasaki Vulcan S in 4.49 s; the BMW R 1300 GS is quicker by 1.53 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 41.4 m for the BMW R 1300 GS (with ABS) and 44.7 m for the Kawasaki Vulcan S (with ABS). The BMW R 1300 GS stops 3.3 m shorter. Calculated top speed: 225 km/h (manufacturer claim) versus 173 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. Open the interactive app (currently in Turkish) to watch the run side by side and change the load.
