yup ct90 is the best there. personally I would keep looking tho, something like a Riva 125 or other small Japanese brand scooter. I feel like q CB125 would be perfect for small bore long distance travel... regardless of what you buy just know your machine and be able to do some repairs as things break no matter what you choose to ride.
seriously avoid the TFR and madass due to both being produced as clone motors with inferior materials. I would ride either as local bikes but not on long trips.
