When Don Castro rode the Triumph 750 with the Fiberglas Works body work, the AMA banned the bike for slip streaming. Crazy, right? (Read the story on our blog). Now get that great photo in a trippy design on a 100% cotton, heavyweight t-shirt. With the cool Don Castro design printed on the front with water based inks, the durability of the tee will last so much longer than that flat track bike did on the track.
