BMW K 1600 GTL vs Yamaha Sirius FI

The BMW K 1600 GTL (2026) and the Yamaha Sirius FI (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 Sirius FI is a cub / underbone with 114 cc, 8.6 hp and 98 kg. Power-to-weight with the rider: 365.5 hp/ton versus 49.6 hp/ton. On this measure the BMW K 1600 GTL is 637% ahead.

0-100 km/h (speedometer): BMW K 1600 GTL 3.34 s, Yamaha Sirius FI not reached (top simulated speed 89 km/h). 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 18.5 m for the Yamaha Sirius FI (ABS unknown, class assumption: no ABS). The BMW K 1600 GTL stops 3.8 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 88 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.
