I am looking into possibly getting a street bike. I have no experience riding one (unless you count a moped as any) so suggestions on which bike i should start with would be greatly appreciated. I am 6'6 tall and 227lbs. I have read that getting a 250 wouldnt fit someone of my stature. Also is there a size difference between the old street and the newer ones today and would it be better to get an older version?
