MX Sports Pro Racing announced today the postponement of the Glen Helen round of the 2010 Lucas Oil AMA Pro Motocross Championship, citing contractual differences with the promoter of the facility in San Bernardino, California.

The second-round event, which was originally scheduled for Glen Helen Raceway on 29 May is now being slated for 11 September at another venue in California.

“This was a difficult decision, but ultimately we simply were not able to come to contractual terms with Glen Helen Raceway,” said Davey Coombs, vice president of MX Sports Pro Racing.

“By moving the date to 11 September we will have time to find a suitable venue. Riders, teams and fans are making travel plans now and we want them to feel secure that we will have an exceptional venue ready in Southern California. We apologise for any inconvenience caused by this change.”

MX Sports Pro Racing does not intend to fill the date of 29 May and will opt to leave the remaining series dates intact, giving competitors and teams Memorial Day weekend off. Details for the 11 September event will be announced soon.
