Morning Kyle, and welcome to the forum.
The bikes bottom about about 150km/h so will easily do your posted speed limit and beyond.
Your BMW dealer would love to sell you a bigger bike, as there is more profit margin in the more expensive machines.
Bear in mind that the Gissette (GS-Ette* patent pending to me) is a compromise of a bike, and can't make up its mind if it is an adventurer, a trail bike, or an Indian commuter in drag.
Bottom line is, yes, it will handle highway speeds easily and yes, it will do it every day.
You may prefer a more road oriented bike for comfort/weather protection (not that it rains in SOCAL).
