Harley-Davidson Heritage Classic vs Kawasaki KLE500

The Harley-Davidson Heritage Classic (2025) and the Kawasaki KLE500 (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 Harley-Davidson Heritage Classic is a cruiser with 1,923 cc, 91.2 hp and 326 kg; the Kawasaki KLE500 is a adventure bike with 451 cc, 44.8 hp and unlisted weight. Power-to-weight with the rider: 227.4 hp/ton versus 162.9 hp/ton. On this measure the Harley-Davidson Heritage Classic is 40% ahead.

In the simulation the Harley-Davidson Heritage Classic covers 0-100 km/h (speedometer) in 3.78 s and the Kawasaki KLE500 in 4.95 s; the Harley-Davidson Heritage Classic is quicker by 1.17 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 49.1 m for the Harley-Davidson Heritage Classic (ABS unknown, class assumption: no ABS) and 41.4 m for the Kawasaki KLE500 (with ABS). The Kawasaki KLE500 stops 7.7 m shorter. Calculated top speed: 194 km/h (estimated from power and drag) versus 150 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 class-average calibration (no accepted model-specific road test) 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.
