After wins in Denver and Oklahoma, Manxman David Knight could win a bonus of 50,000 US dollars if he wins the final round of the 2007 American Endurocross Series.
The prize is only paid if a rider completes a triple crown of victories.
He has already enjoyed a superb season in the United States of America by clinching the Grand National Cross-Country title at his first attempt.
