I've gone back to a gen 1 after owning a 10 plate gen 2 for a couple of Years, and I love it!
The gen 2 is a sports bike with flat bars, no doubt about it, and if that's what you want, then go for it. I tuned mine up to get some awesome power, but you just can't get rid of that sub 4k dullness, something to be aware of!
It handles better than a gen 1, and feels a Hell of a lot lighter. Quite useful really, because you'll be man handling it through petrol stations a lot more often, also the seat isn't as comfy, and you'll be welcoming the rest. :P
Good luck with it!
