BMW K 1600 GTL vs Honda Super Cub C125

The BMW K 1600 GTL (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 K 1600 GTL is a touring bike with 1,649 cc, 158.2 hp and 358 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: 365.5 hp/ton versus 53.0 hp/ton. On this measure the BMW K 1600 GTL is 589% ahead.

In the simulation the BMW K 1600 GTL covers 0-100 km/h (speedometer) in 3.34 s and the Honda Super Cub C125 in 39.63 s; the BMW K 1600 GTL is quicker by 36.29 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 K 1600 GTL (with ABS) and 16.9 m for the Honda Super Cub C125 (with ABS). The BMW K 1600 GTL 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: 226 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 class-average calibration (no accepted model-specific road test) for both. 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.
