Honda GL1800 Gold Wing Bagger vs Honda SH125i

The Honda GL1800 Gold Wing Bagger (2026) and the Honda SH125i (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 Bagger is a touring bike with 1,833 cc, 124.7 hp and 373 kg; the Honda SH125i is a scooter with 125 cc, 12.9 hp and 138 kg. Power-to-weight with the rider: 278.4 hp/ton versus 60.4 hp/ton. On this measure the Honda GL1800 Gold Wing Bagger is 361% ahead.

In the simulation the Honda GL1800 Gold Wing Bagger covers 0-100 km/h (speedometer) in 4.28 s and the Honda SH125i in 19.13 s; the Honda GL1800 Gold Wing Bagger is quicker by 14.85 s. In the 60-0 km/h brake test, braking distance without the 0.3 s reaction time is 14.8 m for the Honda GL1800 Gold Wing Bagger (with ABS) and 16.3 m for the Honda SH125i (with ABS). The Honda GL1800 Gold Wing Bagger stops 1.5 m shorter. The standard 60-0 test is used because one calculated top speed is below 110 km/h. Calculated top speed: 207 km/h (estimated from power and drag) versus 97 km/h (manufacturer claim).

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 Bagger and model-specific parameters calibrated against published road tests for the Honda SH125i.
