I don't think there is too much more exciting, than when a GP riders heads to America for a race, or visa versa. I still remember when Ryan Villopoto did his first GP in Doha, and the whole World sat up watching and I also remember Jeffrey Herlings racing Ironman in 2017. Maybe a little less interesting was the move by Tony Cairoli to race some rounds of the AMA Nationlals, but the Sicilian was at the end of his career and clearly past his best, but it was still entertaining. Below is the Herlings and Cairoli adventures in USA.
