Ken Roczen and Malcolm and James Stewart are surprisingly absent for the weekend’s Red Bull Straight Rhythm at Pomona in California, although top riders include Ryan Dungey, Marvin Musquin, Josh Hansen and Trey Canard in the 450 class. In the 250s, South African Kerim Fitz-Gerald will face Shane McElrath, Dakota Alix and Josh Hill on the Alta electric bike. And there will be a supergoon showdown between YouTube gooners Ronnie Mac and Trevor Piranha.

Open Class Riders: Ryan Dungey, Marvin Musquin, Trey Canard, Josh Hansen, Jeff Alessi, Nico Izzi, Austin Politelli, Darryn Durham, Deven Raper, Tevin Tapia, Kyle Chisholm, Nick Schmidt, Vince Friese, Axell Hodges, Dustin Pipes, Gregg Duffy

250 Class: Shane McElrath, Jordon Smith, Mitchell Oldenberg, Dakota Alix, Kerim Fitz-Gerald, Josh Hill, Colton Aeck, Ben LaMay, Jon Jon Ames, Dare DeMartile

Just like last year, riders will start from an elevated platform then head along the half-mile straight track with whoops, jumps, rhythm sections and a sand section  – all under floodlights.
