I borrowed one whilst my Speed Triple was in for a service. They're great looking bikes and get a lot of attention. I was even getting the
from lorry drivers!
It's got reasonable power, though nothing like a modern sports bike. The main downside, at least for me, was that it was uncomfortable. After an hour of riding I couldn't wait to get off it. I think that this was because of the low clip-on bars. I've been told that you can replace these with higher bars which might help with the comfort. The other strange thing was a (temperature?) warning light that kept coming on, even at normal riding speeds. I forgot to ask the dealer about it.
I can't really offer any other advice than to see what you think on the test ride. There's a lot to like about it and you might not have the same comfort issues as I did.
