Harley-Davidson Sportster S vs Honda CBR650R

The Harley-Davidson Sportster S (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 Sportster S is a cruiser with 1,252 cc, 120.7 hp and 228 kg; the Honda CBR650R is a sport bike with 649 cc, 93.9 hp and 211 kg. Power-to-weight with the rider: 398.3 hp/ton versus 328.2 hp/ton. On this measure the Harley-Davidson Sportster S is 21% ahead.

In the simulation the Harley-Davidson Sportster S covers 0-100 km/h (speedometer) in 2.97 s and the Honda CBR650R in 3.33 s; the Harley-Davidson Sportster S is quicker by 0.36 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 44.7 m for the Harley-Davidson Sportster S (with ABS) and 36.4 m for the Honda CBR650R (with ABS). The Honda CBR650R stops 8.3 m shorter. Calculated top speed: 194 km/h (manufacturer claim) 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 model-specific parameters calibrated against published road tests for both.
