Muscle Milk TWMX Race Series NorCal Spring Cup Continues At MMX Racing

The inaugural stop of the Muscle Milk TWMX Race Series’ Northern California expansion was a smashing success. Hundreds of racers lined up at 408MX in San Jose to take part in the newest racing organization to the area and after a day full of motos, we could not wait to get back to NorCal. Luckily, the time is now as we are currently in the process of packing up the trucks and heading to MMX Racing in Marysville, California.

Located right next to the Yuba River, the track is made of prime river bottom soil, a mixture of sand and loam, that will turn into a number of lines for racers to choose from. The MMX crew has built a number of safe, yet challenging jumps to test a rider’s skill and the wide track allows for even better racing. With all of these features, it is bound to become a favorite stop of racers on the circuit.

Series sponsor Bell will be on hand with their premier helmet, the Moto-9, available for demo and Yamaha will have a selection of bikes and generators on display as well. Muscle Milk’s team will be out in full force to pass out samples of their award-winning drink.

Looking to get some time in on the track? You are in lucky, because MMX will be prep each track before raceday.  The track will be open and prepared on Saturday from 9AM to 2PM and overnight camping is available.

Sunday begins with gates opening at 6:30AM, registration taking place from 6:30 to 8AM, and practice kicking off at 8AM. First moto racing will begin soon after the final practice session is complete.

Want to race? You have two entry methods that will get you in, but we are rather partial to one. Traditional raceday sign-up is available, with cash and now credit card as payment, but you can enter early through our online registration area and use the PayPal option. Payment via PayPal and increased odds at a better first moto gate selection make signing up on the web a viable option, along with this week's online entry prize, courtesy of Muscle Milk. Early entry closes Thursday, April 25th, at 11:55PM.

The New Era Muscle Milk TWMX Race Series snapbacks have arrived! SoCal racers will receive red and black lids, while NorCal racers will be given the grey and black hats.
