Rally driver Ken Block, DC Shoes and Ford Racing have teamed up once again to release a follow-up to "Gymkhana Four: The Hollywood Megamercial." The new chapter, titled "DC Gymkhana Four: Bonus Edit," focuses on Block's behind-the-wheel driving while incorporating never-before-seen shots and all-new angles of previous shots. DC Shoes calls the new edit a "raw, more focused action edit."

According to Block, 44, the co-founder and Chief Brand Officer of DC Shoes, "This edit is way more focused on the driving that I was doing [in Gymkhana Four.] I also think that this video really does a good job demonstrating the difficulty of some of the obstacles I had to negotiate. While I love the original, I think a lot of the fans who just want to see pure driving are going to be stoked on this."

Jeremy Stenberg's new freeriding film "Twitch's 420% All Natural" was released Tuesday through the iTunes Store, just three weeks after its world premiere in Newport Beach, Calif. The film, directed by Jay Schweitzer and produced by Powerband Films, features Stenberg and a posse of riders including Nate Adams, Andy Bakken, Tyler Beremen, Vinnie Carbone, Mike Mason, Jeremy McGrath, Dustin Miller, Dan Pastor, Todd Potter, Ronnie Renner, Myles Richmond, Daniel Sani and Brody Wilson.

Stenberg has said he hopes to transition away from FMX competition to focus on freeriding and filming, and hopes the statement he's making with the new film will help make a post-competitive career possible for himself and for other top freeriders. We caught up with him for more on the film and his future plans.

ESPN.com: You've said before that you've always wished that FMX riders could just go out freeriding and making films and make a career of it, separate from the competition scene, the way some of the top skateboarders and snowboarders have been able to. Now that your "Twitch's 420% All Natural" is getting out in front of the world, how well do you feel the film will help you toward that goal?
Stenberg: I don't know if I've achieved it yet or not, but I know I've put in a solid effort and that is still my ultimate goal. I feel like this film is a step in the right direction, that's for sure.

There isn't a single contest shot or metal ramp in the film and every jump is either natural terrain or something we shoveled out by hand, with one or two exceptions where we used a bulldozer. I grew up freeriding and that's what most of my buddies grew up doing, and I wanted to make sure this movie was truly about freeriding. It's a documentary about what we do when we're out there having fun and not just putting on a show for a crowd.

Global RallyCross driver Stephan Verdier rolled through ESPN to promote the new season that starts Saturday at Charlotte Motor Speedway in Charlotte, N.C., and he answered your questions in a live chat Monday at SportsNation.

Verdier, who finished fourth overall Global RallyCross in 2011, is a veteran rally driver and a former downhill and speed skier. Besides rally driving at summer X Games, Verdier also has competed in Skier X at Winter X Games 2002. For the 2012 Global RallyCross season, Verdier will be teaming his Rhys Millen Racing No. 12 car with the new Disney XD animated series "Motorcity" as a sponsor.

SACRAMENTO, Calif. -- James Stewart won in his return to AMA Motocross, sweeping the motos Saturday in the season-opening Hangtown Motocross Classic.

Stewart, the Suzuki star from Haines City, Fla., raced to his 17th 450 Class victory. In his last full-time season of Nationals competition in 2008, Stewart claimed the premier class championship by becoming the second rider in history to compile a perfect season, winning all 24 motos to join Ricky Carmichael.

"Went better than I thought," Stewart said. "I thought I'd come and struggle a bit, which I did a little. This (season) is one of those things where you continue to build and we got a good start on it. I'm just here to enjoy it. I didn't come to be the fastest. I came to learn the motorcycle. Everything is new. We've got a long way to go. I've been away for a while."

As the AMA Pro Motocross season is set to start Saturday, Ashley Fiolek discusses her preparations for defending her women's championship this season.

Chris TedescoJeremy McGrath has a new drive -- helping increase numbers in the marrow registry.

On Wednesday the motocross industry came out to support the "Be The Match" foundation a registry donor organization helping people diagnosed with leukemia find matching donors.

Leukemia is a type of cancer that affects the blood, bone marrow and lymphoid system. The National Cancer Institute reports that 47,150 new cases of leukemia have been diagnosed since Jan. 1. It is a treatable cancer but matching donors need to be found for bone marrow transplants.

If you want to, you can create quite a personality conflict between Ryan Dungey and James Stewart, the two men expected to tangle for this year's Lucas Oil Pro Motocross Championship, sanctioned by AMA Pro Racing.

Dungey built his career on the factory Suzuki team, left the squad at the end of last season to join his old Suzuki boss, Roger DeCoster, in a new venture at Red Bull KTM. This left Suzuki in need of star power, which they have now found in abundance via Stewart. That means the team Dungey no longer wanted to ride for will now provide his most serious threat for this year's title.

Plus, Dungey and Stewart aren't strangers to each other. Back in 2008, Stewart was dominating the sport to the tune of a perfect season, with 24 moto wins in 24 tries. Dungey, just a second year pro in the stepping-stone 250 class, headed down to Stewart's house for a summer of riding and training. Each week in the post-race press conferences, Dungey would say Stewart is a "great guy" and thank him over and over for letting him ride there. Until someone asked the inevitable question: "What happens when you moved up to the 450 class and have to race James?"

Suddenly Dungey began stuttering and stammering. "He's just a great guy," he said, going back to his stock answer. "I don't know what will happen when we have to race each other. But he's a great guy. A lot of you don't know that, but he's a great guy."

A few months later, the relationship fizzled when they actually did race, at the U.S. Open in October. There was some contact during the regular first-turn melee, and, next thing you know, things weren't the same between the two.

NASCAR Sprint Cup points leader Greg Biffle took a turn driving Brian Deegan's Global RallyCross car earlier this week at Charlotte Motor Speedway and the two motorsports stars discussed their swap Wednesday on ESPN's "NASCAR Now." Watch the video above to see if Biffle will complete the swap and let Deegan drive his Sprint Cup car.

For the past several years, former factory Supercross racer Billy Laninovich was the unfortunate victim of injuries and industry drama that kept him sidelined and off the bike. According to Laninovich, getting hurt in the middle of the 2009 Supercross season was "pretty much the end of my career." But things change. This past December, Laninovich returned to Supercross, finishing ninth overall for the 2012 season. And now, Laninovich is gunning for a spot at X Games Best Whip. With freeride skills on par or beyond with many FMX riders, Billy Laninovich just might have a shot at Best Whip glory. Check the video above for the proof.

On Wednesday the Fédération Internationale de Motocyclisme (FIM) and the International Freestyle Motocross Federation (IFMXF) announced a three-year extension of their partnership with event promoter SportPlus to present the FIM Freestyle MX World Championship tour through 2016 and to introduce a new event, the FIM Freestyle of Nations, debuting in 2013.

"Freestyle Motocross is a very entertaining and exciting discipline combining the show element with top sport," said FIM CEO Stéphane Desprez, in a statement on Wednesday. "The riders work hard and step up their performances with every event. Sportplus gives them the perfect showcase to battle it out for the FIM Freestyle Motocross World Championship. Creating a Freestyle of Nations event will certainly be a boost for the sport."

Desprez took over as CEO of the FIM in October, following Guy Maitre's retirement, and has previous experience as director of competition for the Rugby World Cup and as secretary general for the Fédération Aéronautique Internationale (FAI), the governing body for international air sports.
