Everyone has an opinion as you can clearly see. Ultimately it's up to the person and how you ride/live your life/drive your car/etc.............. In other words I have seen SOOOOO many people say, "Hey how fast is this motorcycle or that motorcycle?" If that's your frame of mind then don't ride, PLEASE!!!! As I hear you say though you are an older guy. The Diavel is only my second bike. I started out on a Street Triple R and rode it for a few months then switched to this. (Bought mine at Eurosport in Fort Worth. I assume you are going to AMS Dallas?) I avoid bad weather, etc.... since I work from home and don't have to travel anywhere I don't want to on my bike. I say get it if you love it. Respect it and any other bike. Gear up, take it easy, but have fun. You didn't make it this long flying by being an idiot. I have flown too and was shocked at how many of the guys who were pilots that shouldn't have been pilots because they were all about HIGH risk and the adrenaline rush. (Scary that they are the ones flying the airlines.....) I always had the same approach to flying as to riding, there's always another day. No need to do it in bad weather (if you don't have to), if you don't feel good, etc......... Live to do it another day. Anyhow, you will definitely get a lot of people that will tell you don't get this for a first bike. It definitely handles different from other bikes due to the large rear end (you have to muscle it more), but don't let that stop you. Take it slow, take the classes, take it slow some more, and just get as much time as you can in areas you are comfortable driving. (In other words I would avoid the freeways, etc.... until you are REALLY ready.) I actually LOVE tooling up and down 35 and 20 now.
Good luck and you will ultimately LOVE the bike!!!!!!!
