Harley-Davidson Heritage Classic vs Honda GL1800 Gold Wing Bagger

The Harley-Davidson Heritage Classic (2025) and the Honda GL1800 Gold Wing Bagger (2026) 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 Harley-Davidson Heritage Classic is a cruiser with 1,923 cc, 91.2 hp and 326 kg; the Honda GL1800 Gold Wing Bagger is a touring bike with 1,833 cc, 124.7 hp and 373 kg. Power-to-weight with the rider: 227.4 hp/ton versus 278.4 hp/ton. On this measure the Honda GL1800 Gold Wing Bagger is 22% ahead.

In the simulation the Harley-Davidson Heritage Classic covers 0-100 km/h (speedometer) in 3.78 s and the Honda GL1800 Gold Wing Bagger in 4.28 s; the Harley-Davidson Heritage Classic is quicker by 0.50 s. In the 100-0 km/h brake test, braking distance without the 0.3 s reaction time is 49.1 m for the Harley-Davidson Heritage Classic (ABS unknown, class assumption: no ABS) and 41.0 m for the Honda GL1800 Gold Wing Bagger (with ABS). The Honda GL1800 Gold Wing Bagger stops 8.1 m shorter. Calculated top speed: 194 km/h (estimated from power and drag) versus 207 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.
