BMW K 1600 GTL vs Yamaha MT-25

The BMW K 1600 GTL (2026) and the Yamaha MT-25 (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 Yamaha MT-25 is a naked bike with 250 cc, 35.4 hp and 166 kg. Power-to-weight with the rider: 365.5 hp/ton versus 146.9 hp/ton. On this measure the BMW K 1600 GTL is 149% ahead.

In the simulation the BMW K 1600 GTL covers 0-100 km/h (speedometer) in 3.34 s and the Yamaha MT-25 in 6.35 s; the BMW K 1600 GTL is quicker by 3.01 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 41.0 m for the BMW K 1600 GTL (with ABS) and 48.0 m for the Yamaha MT-25 (ABS unknown, class assumption: no ABS). The BMW K 1600 GTL stops 7.1 m shorter. Calculated top speed: 226 km/h (estimated from power and drag) versus 147 km/h (derived (GPS ratio)).

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 Yamaha MT-25.
