What style helmet? Full, modular, 3/4, half helmet?
Houston-native Kevin Schwantz wore a full face Arai with Lone Star design when he raced Superbike back in the 80s & 90s. There may be a replica out there somewhere. Maybe try fleaBay.
Troy Lee Designs has this one with UT's Bevo logo on it. Troy Lee does custom painted helmets, and I'm sure their are other paint shops willing to do a custom design.
