Many people I now in the FL and TX motorcycle community don't ride as much in the heat of Summer and can't wait for "Fall riding season" to begin. Even in Ontario, we get 100 degree including humidity days when convertibles aren't the most practical and Summer's are only getting hotter.
They're really not the best daily drivers when you ideally want 70-90 and sunny
Most of these are convertibles with a tarp over a folding frame, closer to a boat top. I don't think too many owners actually plan to regularly drive with the top up .... on purpose.
