On May 22, 2016, Jake Moss tested positive for Ostarine following a drug test conducted by ASADA (and affiliate of WADA) at the Murray Bridge 450 Nationals. He was suspended awaiting a hearing. Moss has now been banned from competition for four years for violating Articles 2.1 and 2.2 of Motorcycle Australia’s 2015 Anti-Doping Policy. Jake’s brother Matt also failed the same drug test for the same reason, but his case has not been announced. In his last official statement about the drug charges, in August, Matt said, “I am confident of being cleared and I look forward to returning to the sport I love as soon as possible.”
Jake Moss said, “As you may know, I recently announced my retirement from racing. As I said at the time, this decision to retire was based upon my decision to focus on my family and career away from competitive motocross and supercross racing. I have recently been advised through Motorcycling Australia and ASADA that I have allegedly tested positive to Ostarine, which is prohibited substance under the World Anti-Doping Code. I do not accept the results of the test and I am in the process of challenging those results through the appropriate processes.”
However, Motorcycling Australian said that Jake Moss never filed an appeal and thus the four-year ban will stand (the starting date would be July 15, 2016 and got to July 14, 2020). During this period of time Moss willbe now ineligible to participate, as an athlete or support person (including coaching or officiating), until he has completed his four-year ban and the ban includes using member facilities.
The AMA did drug test several times during last year’s AMA Supercross series. The tested Jason Anderson, Trey Canard, Ryan Dungey, Chad Reed and Ken Roczen at Santa Clara. They tested Justin Boggle, Justin Brayton, Marvin Musquin, Weston Peick and Broc Tickle at Foxboro. They tested Vince Friese, Josh Grant, Cole Seely, Eli Tomac and Jake Weimer at New York. All 15 of the tested riders passed with flying colors.
