Former world champ Tim Gajser heads to California this week for some supercross practice prior to taking on America’s best at the $1 million Monster Cup in Las Vegas at the weekend.

He’ll face US outdoor champ Eli Tomac, Marvin Musquin, Jason Anderson and Dean Wilson as well as Davi Millsaps out for the first time on his new factory Yamaha, plus Justin Barcia making his debut as a Honda privateer.

Broc Tickle will have his first race on the factory 450 KTM after replacing Ryan Dungey, and Christian Craig fills in for Cole Seely who has had surgery on a finger injury.
