The 2011 Monster Energy AMA Supercross, an FIM World Championship, heads east this weekend as it visits Houston’s Reliant Stadium for the sixth race of the season.

Last weekend in Anaheim, San Manuel Yamaha’s James Stewart led the field from start to finish, registering his third Supercross class victory of the season.

Stewart opened the main event last weekend in Anaheim by capturing his second holeshot of the season.

Stewart held a consistent four second lead through all 20 laps over second place finisher and Monster Energy Kawasaki’s Ryan Villopoto to dial in his 40th Supercross class career victory.

“Tonight was great,” said Stewart. “I had a great heat race and the Yamaha pulled a great start. The track was tough and I think the skills really came into play.

“I just rode 20 good laps, I’m feeling comfortable on the motorcycle and the good part about it is we haven’t changed anything on it since Anaheim 1. The bike was just fantastic tonight.”

TwoTwo Motorsports’ Chad Reed trailed Villopoto throughout the race to earn a third place finish. Reed’s second consecutive podium finish last weekend advanced him from fifth to third in the championship point standings.

Supercross class rookie and American Honda’s Trey Canard locked in in his fourth top-five finish last weekend, which keeps him in a comfortable fourth place position, three points behind Reed.

“It was nice to get out in front seeing where guys are strong and where I need to work,” said Reed. “Weeks prior to this, I felt I didn’t have the rhythm nor the comfort to push it to that level.

“I feel I gained a lot [of comfort] racing tonight and feel we as a team gained some necessary improvement. Everything at this level helps, and we took a leap forward with knowing where I need to be stronger.”

Defending 2010 supercross champion and Rockstar Makita Suzuki’s Ryan Dungey started the race mid-pack, but was forced to pull off the track late on lap seven as a result of a derailed bike chain.

With a DNF, Dungey lost his third place spot to Reed and now sits in fifth place with 79 points, 38 behind leader Stewart.

The Western Regional Supercross Lites class will take a short one-week break as Pro Circuit/Monster Energy/Kawasaki’s Josh Hansen controls the points lead in the division after a well-deserved win, marking the third of the season.

As the Western Regional Lites class takes the weekend off, the Eastern Regional Lites class is ready to amplify the season hype with a fresh group of young riders set to stage a run at the title.

Stewart’s younger brother, Malcolm, makes his Supercross Lites class debut this weekend, riding for Team Suzuki City.

James Stewart finished his rookie season in the Western Regional Lites class runner-up for the title, winning three of eight races and posting two additional podium finishes. Time will tell if his younger brother is able to follow in his tracks.

Last year in front of 44,624 fans from Houston’s Reliant Stadium, Monster Energy Kawasaki’s Ryan Villopoto won his seventh Supercross class race of the year.

Monster Energy/Pro Circuit/Kawasaki’s Christophe Pourcel captured his fifth win of the Supercross Lites Eastern Regional Championship season and claimed his second consecutive title in the process.

Since 1974 Houston has been on the Supercross class schedule. From 1974-2002 the Houston Astrodome served as host to the race before the race was moved to Reliant Stadium in 2003.

The first Supercross class race in Houston was on 15 March 1974, where Jim Pomeroy earned the win. In the Supercross Lites competition, Eddie Warren won the first race held in Houston on 20 April 1985.

Jeremy McGrath, the all-time winningest supercross rider, shares the all-time win record along with Mark Barnett with five.
