Glen Helen's U.S. GP has been left off the calendar for season 2012.

Youthstream has released a statement regarding the loss of Glen Helen’s United States round of the Motocross World Championship in 2012.

The pair has confirmed that their relationship is a strong one, however the lack of success in attracting U.S. riders and teams has forced them to abandon the round for at least next season.

Youthstream and Glen Helen will however continue working on having a U.S. GP in the future with the presence of the top American riders.

“It has certainly been great working with Bud Feldkamp, Lori Byrant and all the Glen Helen staff, they welcomed the world championship, and they are very friendly and professional,” said Youthstream president Giuseppe Luongo.

“Glen Helen is one of the best motocross tracks in the world and I really hope to be able to return one day. During this time together I have found a true and trustful friend in Bud.”

Bud Felkamp, the owner of Glen Helen, said he had a great respect for the world championship organisers.

“Working with Youthstream and the FIM has been a great experience, a real pleasure,” he added. “The world championship teams are very well organised and the riders are really fast – the races were just spectacular.

“We are hoping to find support from the American motocross industries so that we can continue organising the U.S. GP with the top U.S. and European riders, and have the race of the century – it would be such a big loss for the American fans if we lose this race.

“Glen Helen is the best track in the world and we would love seeing Villopoto, Stewart, Dungey, Reed and all our other great riders battle it out against the likes of Cairoli, Desalle, Roczen – so we count on the support of the American riders, fans and industry.”

Glen Helen held its first U.S. GP last season, holding two events before it was decided to cancel the event for 2012.
