Honda GL1800 Gold Wing vs Yamaha R25

The Honda GL1800 Gold Wing (2026) and the Yamaha R25 (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 Honda GL1800 Gold Wing is a touring bike with 1,833 cc, 124.7 hp and 393 kg; the Yamaha R25 is a sport bike with 250 cc, 35.4 hp and 169 kg. Power-to-weight with the rider: 266.5 hp/ton versus 145.1 hp/ton. On this measure the Honda GL1800 Gold Wing is 84% ahead.

In the simulation the Honda GL1800 Gold Wing covers 0-100 km/h (speedometer) in 4.46 s and the Yamaha R25 in 6.40 s; the Honda GL1800 Gold Wing is quicker by 1.94 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 41.0 m for the Honda GL1800 Gold Wing (with ABS) and 40.0 m for the Yamaha R25 (ABS unknown, class assumption: no ABS). The Yamaha R25 stops 1.0 m shorter. Calculated top speed: 207 km/h (estimated from power and drag) versus 158 km/h (GPS measurement).

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 Honda GL1800 Gold Wing and model-specific parameters calibrated against published road tests for the Yamaha R25.
