THIS IS WHERE YOU FIND OUT WHAT YOU'RE MADE OF
15 CLASSES. ONE STANDARD. ZERO EXCUSES.
WHY 3 MOTOS?
BECAUSE ONE MOTO DOESN'T TELL THE WHOLE STORY.
AT 543 MX EVERY RIDER GETS THREE CHANCES TO PROVE THEMSELVES.
FIVE LAPS. FOUR LAPS. THREE LAPS.
THAT'S NOT JUST OUR FORMAT, THAT'S OUR NAME.
THREE MOTOS MEANS THE BEST RIDER ON THE DAY WINS.
THAT'S THE ONLY KIND OF CHAMPION WE CROWN HERE.
5 LAPS. 4 LAPS. 3 LAPS. THAT'S 543.
