I've often wondered about the Cub-90: wouldn't it be cheaper and more effective to just carry a large sign saying "I am gay"? (obviously in the derogatory rather than the homosexual sense of the word).
Of course, given a choice between a C-90 and walking, the little Honda wins... no-one can see your face when you wear a helmet!
Plus without the C-90 there would be no such thing as delivery pizza. A motorcycle magazine I used to read fitted nitrous to one and it lasted a minute or so with an estimated 40bhp until flames started licking out of the engine!
