Roy competed in the USA as a privateer for a number of years, where he raced both the AMA Motocross and Supercross classes.
Unfortunately, Roy was unable to secure a full factory ride after that, and switched between several private Honda teams.
Roy has proven extremely competitive during his part-time forays in the AMA championship, regularly showing top 10 speed on production-based, 2-stroke equipment.
In 2008, Roy competed in just a single CMRC national event, and announced that the upcoming Montreal Supercross would be his final pro race.
To the delight of the hometown crowd, Roy led wire-to-wire and claimed the victory, capping off a stellar career.
