New here

Hi all, finally starting to look hard at getting a first bike. My home is in Florida, but I work overseas. Anyways, I am 5'10" 31 Y/O and depending on if I am hitting the gym I weigh from 190 - 210 lbs. 32" inseam. Looking at getting a 250r since I have no experience, but I am starting to wonder if a 650R is more suited for me. I will probaly get the bike in August, so I have plenty of time to research. Looking forward to all the info to gather here.
