Online Entry Now Open For Final Rounds Of Muscle Milk TWMX Race Series Fall Cup

To say that our inaugural season as race promoters was a moderate success would be an understatement. Thanks to support from our sponsors, tracks, and most importantly, the racers themselves, the Muscle Milk TWMX Race Series quickly became the one of the biggest amateur racing organizations in Southern California. Rather than rest on the accomplishment, we are already planning for bigger and better things in 2013. But before we can get to that, we’d like to finish out an amazing year with two days at Glen Helen Raceway.

The world famous layout that is Glen Helen needs no introduction, and for that reason, it is the site of our final races of the year. Each previous stop at the San Bernardino circuit has yielded record turnout numbers, and we know that tradition will continue this weekend as SoCal’s finest racers vie for Fall Cup championships. We have a mountain of products to congratulate the winners and top finishers of each class with, thanks to our series sponsors, and after 12 months of waiting, we will give away the 2012 Yamaha YZ450F that has been on display at each round. You must be present SUNDAY to win any of the goods, so be sure to sign up now.

Online entry for both rounds of the Muscle Milk TWMX Race Series at Glen Helen is now open at Payment via PayPal and increased odds at a better first moto gate selection make signing up on the web a viable option.  Early entry closes FRIDAY, NOVEMBER 30TH, AT 11:55P.M.

Want to add a brand new 2012 Yamaha YZ450F to your garage? Be at Glen Helen this weekend.
