Honda CB125F vs Honda GL1800 Gold Wing Bagger

The Honda CB125F (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 Honda CB125F is a naked bike with 124 cc, 10.7 hp and 117 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: 55.9 hp/ton versus 278.4 hp/ton. On this measure the Honda GL1800 Gold Wing Bagger is 398% ahead.

In the simulation the Honda CB125F covers 0-100 km/h (speedometer) in 21.61 s and the Honda GL1800 Gold Wing Bagger in 4.28 s; the Honda GL1800 Gold Wing Bagger is quicker by 17.32 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 17.3 m for the Honda CB125F (ABS unknown, class assumption: no ABS) and 14.8 m for the Honda GL1800 Gold Wing Bagger (with ABS). The Honda GL1800 Gold Wing Bagger stops 2.5 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 100 km/h (manufacturer claim) 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 model-specific parameters calibrated against published road tests for the Honda CB125F and class-average calibration (no accepted model-specific road test) for the Honda GL1800 Gold Wing Bagger.
