BMW K 1600 GT vs Honda Activa 125

The BMW K 1600 GT (2026) and the Honda Activa 125 (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 BMW K 1600 GT is a touring bike with 1,649 cc, 158.2 hp and 343 kg; the Honda Activa 125 is a scooter with 124 cc, 8.3 hp and 107 kg. Power-to-weight with the rider: 378.6 hp/ton versus 45.7 hp/ton. On this measure the BMW K 1600 GT is 729% ahead.

In the simulation the BMW K 1600 GT covers 0-100 km/h (speedometer) in 3.27 s and the Honda Activa 125 in 36.16 s; the BMW K 1600 GT is quicker by 32.89 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 GT (with ABS) and 17.9 m for the Honda Activa 125 (ABS unknown, class assumption: no ABS). The BMW K 1600 GT stops 3.1 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 90 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 class-average calibration (no accepted model-specific road test) for the BMW K 1600 GT and model-specific parameters calibrated against published road tests for the Honda Activa 125.
