BMW R 1300 RT vs Honda Super Cub C125

The BMW R 1300 RT (2026) and the Honda Super Cub C125 (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 BMW R 1300 RT is a touring bike with 1,300 cc, 143.5 hp and 281 kg; the Honda Super Cub C125 is a cub / underbone with 123 cc, 9.7 hp and unlisted weight. Power-to-weight with the rider: 403.1 hp/ton versus 53.0 hp/ton. On this measure the BMW R 1300 RT is 660% ahead.

In the simulation the BMW R 1300 RT covers 0-100 km/h (speedometer) in 3.37 s and the Honda Super Cub C125 in 39.63 s; the BMW R 1300 RT is quicker by 36.26 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 14.8 m for the BMW R 1300 RT (with ABS) and 16.9 m for the Honda Super Cub C125 (with ABS). The BMW R 1300 RT stops 2.1 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 229 km/h (estimated from power and drag) versus 93 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 model-specific parameters calibrated against published road tests for the BMW R 1300 RT and class-average calibration (no accepted model-specific road test) for the Honda Super Cub C125. 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.
