Harley-Davidson Heritage Classic vs Honda CBR650R

The Harley-Davidson Heritage Classic (2025) and the Honda CBR650R (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 Harley-Davidson Heritage Classic is a cruiser with 1,923 cc, 91.2 hp and 326 kg; the Honda CBR650R is a sport bike with 649 cc, 93.9 hp and 211 kg. Power-to-weight with the rider: 227.4 hp/ton versus 328.2 hp/ton. On this measure the Honda CBR650R is 44% ahead.

In the simulation the Harley-Davidson Heritage Classic covers 0-100 km/h (speedometer) in 3.78 s and the Honda CBR650R in 3.33 s; the Honda CBR650R is quicker by 0.45 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 36.4 m for the Honda CBR650R (with ABS). The Honda CBR650R stops 12.7 m shorter. Calculated top speed: 194 km/h (estimated from power and drag) versus 220 km/h (manufacturer claim).

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 the Harley-Davidson Heritage Classic and model-specific parameters calibrated against published road tests for the Honda CBR650R.
