Yes.
Motard - somewhat, just due to the fact that it’s 5 speed. Could use another gear. I still ride highway all the time, just would think twice about anything over 30 miles on highway.
250 - a bit less of an issue.
Powerwise, while they won’t be the peppiest things in the world at those speeds you will be just fine going with traffic. Just don’t expect to do a power bomb blast past people.
