I am only 6'2" - but 36" inseam and 37" sleave...
My first ride was a Katana 750 (rode it all over North America from Deal's Gap to Death Valley).
Next was a DL1000 (VSTROM) - lots of comfy miles there too! But for a first bike, I would recommend the wee-strom (DL650) instead.
Current ride is a ZX14 with lowered pegs - LOVE IT - but not a good choice for your first bike...
The KLR650 is also a decent choice for a first ride - I have two buddies who have put major miles on theirs - one is 6'6", and the other is only 5'10" (but pushing 300lbs)...
