WATCH LIVE: Eli Tomac defends Lucas Oil Pro Motocross points lead at Glen Helen


The Lucas Oil Pro Motocross Championship is in the epicenter of the sport this weekend – Southern California. Glen Helen – a track known for challenging riders with its steep hills – will be the site of the second round of the series.

Live coverage begins at 4 p.m. ET with the pre-race show streaming live online on NBC Sports Live Extra and First motos in both classes get underway at 5 p.m. ET, with second motos to follow at 7 p.m. ET. All motos will be streamed live online, and second motos will also air live on NBCSN at 7 p.m. ET.

Last week in the 450 Class, Eli Tomac had a win of historic proportions. His one-minute, 31-second victory in the second moto was the largest margin of victory in the premier class since Ricky Carmichael lapped the field in 2006. Things can change quickly though – Ryan Dungey and the rest of the field have had another week to get their bikes dialed in, and they’re anxious to prove that Tomac won’t repeat his feat.

“His performance was great by all means,” Dungey said at last week’s post-race press conference. “But I also believe – not in a cocky way – that he’s at his best – him, the bike. I see a lot of improvement on our side still yet to come. I definitely have a lot more than we showed today.”

Also in the picture is Ken Roczen, the defending champion of the 450 Class. The RCH Suzuki rider was hampered by a back injury last weekend, but he is feeling much better this week, and it’s showing out on the track. He ended today’s practice as the top qualifier in the premier class.

In the 250 Class, a deep field of title contenders is now thinning out. Justin Bogle (shoulder) and Cooper Webb (ankle) are both out of today’s race after suffering injuries last week at Hangtown. The stage looks to be set for a season-long showdown between Jeremy Martin and Marvin Musquin, the two riders who currently share the points lead entering today’s race.

Glen Helen was the site of Martin’s breakout ride last season – the first of many wins on his way to a championship. The Yamalube/Star Racing/Yamaha rider was the fastest qualifier in practice this morning and will be looking to turn that into his second straight race win.
