Hi Chet.
It's going to be more expensive to run than a Fazer, that's for sure.
Insurance depends on age & experience, but mpg is governed by the right wrist. I can get nearly 200 miles out of a tankful, or as little as 120 if I'm in hooligan mode.
Rear tyre will need replacing in 3 to 3500 in the UK at about £170 a pop (don't listen to the Yanks with their stories of ultra high tyre mileage - they must all ride like pussies
It's not just the 0 - 60's that are fun on this beast. 60 - 100+ is just a flick of the wrist.
Go for it & enjoy.
