There are exceptions to every rule, and mine was a Honda CB250RS. I've never heard anything but praise for these bikes: the only mild criticism I've encountered (which, coincidentally, appeared either on this site or its predecessor) was that the test example supplied by Honda to the UK media was, for some reason, "blue printed" to outpace the simultaneously-available Honda 250N Superdream.
However, my RS was a lemon. It was purchased from a dealer from whom I've obtained most of my motorcycles, but the 250RS was the only duff one he ever sold me. The kickstart falling off halfway through one of the Mersey Tunnels was typical of the problems I had with it.
It's obvious that I can't be right and everyone else wrong. The only explanation for this phenomenon is that it was a "Jinx Bike"; that the combination of the RS and myself was like a romance that was doomed from the beginning. We should never have met.
Can the panel cite any other examples of a model of motorcycle that worked well for everyone but themselves?
