Not a bad start.
For what it's worth, I make the following suggestions.
Depending on how much you like debauchery and decadence, 1 day in Vegas is not enough. (Some might say that 1 day in Vegas is too much)
I would divert your Salt Lake to Moab further east to see more of Southern Colorado. There you'll find some of the most amazing motorcycle roads in all the US. Silverton, Ouray, Telluride, etc cant be beat.
If you're going to Sante Fe, be sure to stop in Taos. You can also visit Madrid, where Wild Hogs was filmed. Young Guns was filmed in the next town over.
You will circle Monument Valley without seeing it. Dont do that. Ever seen all those John Wayne movies with those amazing rock formations? Maybe you saw them in the Roadrunner cartoons, too.
Ask the Californians for the correct timing to ride up the coast. The scenery is amazing. It's a great drive, but choked with traffic almost all the time.
Good luck. Have fun.
