Moto2 podium-sitter Anthony West has been stripped of his seventh-place finish at Le Mans and banned from competition for one month for a doping transgression.
West, who has finished runner-up in the last two Moto2 races, gave a sample back at Le Mans in May which was found to contain traces of a prohibited substance.
Organizing body FIM, the Federation Internationale de Motorcyclisme, said that West's sample contained Methylhexaneamine, on its list of banned specified stimulants.
As a result the FIM has disqualified the 31-year-old Australian from the French Grand Prix results, and has also banned him for one month from competing in an FIM-sanctioned or FIM-affiliated race, effectively immediately. West has five days to appeal the decision.
Methylhexaneamine is considered a stimulant as it increases heart rate and blood pressure, and can be found in training supplements, although it isn't always identified on the product. Should West's appeal prove unsuccessful, he will miss the Moto2 finale at Valencia next weekend.
