Their successes in MotoGP and WorldSBK have made them legends of their disciplines and while it’s highly unlikely we’ll see them line up on the same grid in the future they share more than their status as world champions. Alex Ferguson famously said “some players have world class moments, others have world class careers.” The legendary soccer manager was talking about the difference between being a transcendent player and one that only ever flashes their potential. If you want to be a legend you have to do it every time you lace up your boots. If you want to be a legend of motorcycle racing you have to be all-in at every opportunity. Any time that you’re on the bike is an opportunity to assert your dominance. Racing is the ultimate test of nerve. Can you dig deep enough into your soul to constantly get the most from yourself? Can you take the will out of your rivals? New rivals Márquez and Rea have both done this consistently but this year both faced their toughest tests. For Márquez it’s been the coming of a rookie sensation, Fabio Quartararo, and for Rea it’s been a MotoGP refugee, Alvaro Bautista. Both rookies came to the 2019 season with something to prove.
