Is the CB1100 no more?

For sure in the U.S. mph is the dominant scale, km/h the secondary and/or optional scale. Some states are very strict about this and make bikes [imported] from Canada reverse the speedometer scales, if permanently printed on dial gauges.

In Canada it is the reverse (dominant km/h, secondary mph), but I don't think it is enforced. My Aprilia had mph dominant scale, km/h secondary.

Also keep in mind, there are many counties in the U.S. that post speed limits in km/h. So that may have some other effect on supplying secondary km/h scales.

Nevertheless, with many modern vehicles using digital and "smart" displays, the issue is becoming largely moot.
