I buy and sell bikes all the time. Custom street bikes/street legal track day bikes are my hobby and NOBODY gets to ride one of my bikes unless they have put cash, in full, in my hand first. I am happy to take it anywhere they choose within a reasonable distance to be checked out and will let an insured shop mechanic ride one (while I watch) but not a private rider. Sorry, been there, done that, and have been burned having to fix the bike myself and the rider attempt to sue me for his medical bills.
The R/R issue is the only known and no it wasn't fixed on the '10 so make sure it has been or you will be spending time at the dealer having it changed. Other than that 2010 was the best year made so if it's clean, checks out, and is priced right go for it
