There are several different iterations of the bike. The Standard, Classic, Tourer, Touring, and Roadster. They are all basically the same bike until these newfangled things came out in 2020. The R3T is probably the most different though.
Any initial bugs were ironed out by 2009, but any year or variation should be a good bike as long as it doesn't jump out of 2nd hear on hard acceleration. Find the one you like and put a lot of miles on it.
