I rode an FZ1 for a season. Nice bike. But I was never really comfortable with it. I spent some time, miles, and money trying to make it fit me -- Corbin Beetle Babs and a Corbin seat. I finally decided that it just wasn't the bike for me and moved on. But it has a lot of spirit and was fun to ride. It just didn't fit me well. The 06's are getting terrible reviews from owners and the rags. Really bad low end hesitation from a poorly done EFI remapping. The new 05's were snatched up pretty quick once the word was out that the 06's had this problem.
Right before I decided to pick up a 919, I had the FZ6 on my short list. Took it for a test ride too. Really neat little bike. Nice price too. In the end I went with the 919 due to smoothness, quality, Honda name, and the larger engine.
