Honda Activa 125 vs Honda CBR650R

The Honda Activa 125 (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 Honda Activa 125 is a scooter with 124 cc, 8.3 hp and 107 kg; the Honda CBR650R is a sport bike with 649 cc, 93.9 hp and 211 kg. Power-to-weight with the rider: 45.7 hp/ton versus 328.2 hp/ton. On this measure the Honda CBR650R is 619% ahead.

In the simulation the Honda Activa 125 covers 0-100 km/h (speedometer) in 36.16 s and the Honda CBR650R in 3.33 s; the Honda CBR650R is quicker by 32.83 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.9 m for the Honda Activa 125 (ABS unknown, class assumption: no ABS) and 13.1 m for the Honda CBR650R (with ABS). The Honda CBR650R stops 4.8 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 90 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.
