Yamaha rider - considering a new Rocket III - would like advice

If I went to a biker bar, Harley dudes would scoff at the S10.

They would secretly admire the Roadster (but not let on, of course.)
 
That's nice , I am happy for you having all these fantastic multi functional bikes that are all purpose built to suite your needs, We have a few Pubs around here that are frequented by the so called outlaw motorcycle clubs but no "Biker Bars" that I know of, I have been into a couple of their Club Houses as a guest of a Member that I have known since childhood and I have seen several fully patched up gang members riding Rockets and early Triumphs, and I have parked my rocket outside of these pubs with no sign of rejection from the guys ,maybe they don't feel threatened by a big old tattooed cowboy like me on a Rocket.
 
You'll love the bike and the balance you'll get . The only thing I can add if that my r3t gets real warm on my ****** if it's 30+ degrees and I'm in stop and go traffic too long. Could be my Corbin seat, but take the plunge and come ride!

Happy hunting
