BMW K 1600 GTL vs Honda SH125i

The BMW K 1600 GTL (2026) 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 BMW K 1600 GTL is a touring bike with 1,649 cc, 158.2 hp and 358 kg; the Honda SH125i is a scooter with 125 cc, 12.9 hp and 138 kg. Power-to-weight with the rider: 365.5 hp/ton versus 60.4 hp/ton. On this measure the BMW K 1600 GTL is 505% ahead.

In the simulation the BMW K 1600 GTL covers 0-100 km/h (speedometer) in 3.34 s and the Honda SH125i in 19.13 s; the BMW K 1600 GTL is quicker by 15.79 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 16.3 m for the Honda SH125i (with ABS). The BMW K 1600 GTL stops 1.5 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 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 class-average calibration (no accepted model-specific road test) for the BMW K 1600 GTL and model-specific parameters calibrated against published road tests for the Honda SH125i.
