Honda CBR650R vs Honda SH125i

The Honda CBR650R (2025) and the Honda SH125i (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 CBR650R is a sport bike with 649 cc, 93.9 hp and 211 kg; the Honda SH125i is a scooter with 125 cc, 12.9 hp and 138 kg. Power-to-weight with the rider: 328.2 hp/ton versus 60.4 hp/ton. On this measure the Honda CBR650R is 443% ahead.

In the simulation the Honda CBR650R covers 0-100 km/h (speedometer) in 3.33 s and the Honda SH125i in 19.13 s; the Honda CBR650R is quicker by 15.80 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 13.1 m for the Honda CBR650R (with ABS) and 16.3 m for the Honda SH125i (with ABS). The Honda CBR650R stops 3.2 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 220 km/h (manufacturer claim) versus 97 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.
