i think all bikes have there issues and certainly the number of them sold on the road would denote the number of them having potantil issues, i guess its a relevent thing more sold more likley there will be issues. I have owned my share of bikes over time, never an HD so i cannot and will not speak from experience. But upkeep and maintanance is a very big factor, i was out this summer at a local stop over coffee place (tims for you canadians) and an hd guy was chatting about the problems he was having with his 2 year old bike, the thing was dirty as heck and if he had not told me the age i might have guessed it was 10-15 years old, you could tell he did not care for it, just rode it then complained if it broke down, many of the "current" HD riders are yuppies that have no clude how to even change their own oil, so i suspect that is part of it. But the HD do seem to have their issues with heat apparently these days, but my speedy can sure get pretty warm too on a hot day.
