CFMoto 250NK vs Kawasaki Vulcan S

The CFMoto 250NK (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 CFMoto 250NK is a naked bike with 249 cc, 26.2 hp and unlisted weight; the Kawasaki Vulcan S is a cruiser with 649 cc, 59.9 hp and unlisted weight. Power-to-weight with the rider: 111.2 hp/ton versus 226.5 hp/ton. On this measure the Kawasaki Vulcan S is 104% ahead.

In the simulation the CFMoto 250NK covers 0-100 km/h (speedometer) in 8.91 s and the Kawasaki Vulcan S in 4.49 s; the Kawasaki Vulcan S is quicker by 4.42 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 48.0 m for the CFMoto 250NK (ABS unknown, class assumption: no ABS) and 44.7 m for the Kawasaki Vulcan S (with ABS). The Kawasaki Vulcan S stops 3.3 m shorter. Calculated top speed: 115 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.
