BMW R 1300 RT vs Kawasaki Vulcan S

The BMW R 1300 RT (2026) 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 RT is a touring bike with 1,300 cc, 143.5 hp and 281 kg; the Kawasaki Vulcan S is a cruiser with 649 cc, 59.9 hp and unlisted weight. Power-to-weight with the rider: 403.1 hp/ton versus 226.5 hp/ton. On this measure the BMW R 1300 RT is 78% ahead.

In the simulation the BMW R 1300 RT covers 0-100 km/h (speedometer) in 3.37 s and the Kawasaki Vulcan S in 4.49 s; the BMW R 1300 RT is quicker by 1.11 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 41.0 m for the BMW R 1300 RT (with ABS) and 44.7 m for the Kawasaki Vulcan S (with ABS). The BMW R 1300 RT stops 3.7 m shorter. Calculated top speed: 229 km/h (estimated from power and drag) 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.
