sounds like your experience is in line with a lot of reviews, have discounted them permanently now. looking for a 600 to share the garage with my blackbird, as my blackbird has a fat arse to get down through some tightish twisties that we encounter on the WB rideouts as Burbler can testify to with his one plus i'm not as light nimble and flexible as i was in my yoof
sounds like you know the ZZR pretty well, will have to bring it over to you for a tune and once over when i get it
