That's just what you need to do-ride it first. Every bike is different for every rider. The FJR is a great bike for long rides, it will eat up the miles no problem and the power from that 1300 is real nice-smooth! Jump over to the FJRforum.com, after logging in spend some time reading all about the bike and pricing too.
They are having a FJR national gathering in LaCrosse in mid September called NAFO (National FJR Owners) If you get one or really want to learn how people farkle their bike for them this is the place to be. All bikes are welcome if you wanted to meet and ride with some FJR's.
I would go but I have been to LaCrosse (awesome riding) before and chose to ride my Hondapotamas to the Eastern FJR owners meet a week later in Maggie Valley NC. Never been that far east, Oh boy!
Feel free to pm me if you have any questions, I am still real involved with the forum under a different name. Gotta hide from the NSA
