I haven't got one now, but I've had three R1s.
I had one of the very first batch to come into the UK back in 1998:
Then I had a 2003-spec one in 2004 when they were boing sold off cheaply:
And then I had one of the lovely 50th anniversary ones:
I enjoyed all of them, but I personally wouldn't go back to one. As I've got older I've not enjoyed the "intense" riding experience of race replicas as much as I used to, plus the roads round my way have consistently got busier and busier, making riding a race replica (and to a lesser extent any fast bike) increasingly frustrating. But I do have a second generation FZ1 which I love, and which I'd certainly say is very different in character from any of the R1s I've owned, as it hasn't got the "locked-in" riding position of a race replica and is a rather more chilled riding experience while still being plenty fast enough! Personally I don't want to own two bikes at the same time any more, though I have in the past, so it's a matter for me of having the best single bike for my wants and needs. Even though I work part-time, from home, I just don't find the time to make it worth running two bikes concurrently.
In my view, if you haven't owned an open-class race replica before I'd say that you should seriously consider having one at some point in your biking life (though, as others have said, you would be best to shop around rather than definitely going for the one that's got you thinking about it in the first place). If you go for an older R1, as some people on here have suggested, you're unlikely to lose all that much money if you sell it after a while because it isn't doing it for you. Do you have a bike shop near you that is likely to let you have a demo ride? If so that would seem to be a good first step. I'm lucky in that my local dealer has always let me have demo rides whenever I want, and it is a great help.
