The two Australian events will be the first time Villopoto has ever raced in Australia.

21 year old Villopoto was leading the 2010 Monster Energy AMA Supercross series with an incredible seven race wins, the most of any rider in 2010, until a broken leg forced him out of the championship. He is considered to be the future dominant star of the sport along with his arch rival, Ryan Dungey who went on to win this year's AMA Supercross series.

In association with American Honda, MXSports Pro Racing announces the introduction of the Honda CRF150 Cup. The Honda CRF150 Cup is a pair of special races held in conjunction with the final two rounds of the Lucas Oil AMA Pro Motocross Championship, held at Steel City and Pala Raceways, in Pennsylvania and Southern California, respectively. The races, which will be held the same day as both nationals and on the exact same track as the pros, will take place on September 4 (Steel City) and September 11 (Pala) and are designed as a platform to showcase the next generation of motocross talent.

Says Powersports Press Manager Bill Savino "Honda is ramping up its release of 2011 models. We're proud to unveil our newest race bikes, the CRF450R and CRF250R motocrossers, plus a wide assortment of Honda off-road machines that have remained extremely popular with recreational riders over the years. With these models for 2011 and more to follow, this is certainly going to be a great year for riding enthusiasts."

The Class of the Open-Class MX Bikes: Honda CRF450R

Long regarded as the bike of choice in the big-bore motocross division, the 2011 CRF450R incorporates a host of improvements that will help this bike retain its standing as the yardstick by which all others in the class are compared. Various tweaks to the engine tuning broaden the already prodigious power band - more low-end pull and midrange grunt - while also enhancing throttle response via a new throttle body.

With the 2010 Lucas Oil AMA Pro Motocross Championship season halfway over, premier class rookie and Rockstar/Makita Suzuki rider Ryan Dungey continues to lead the way in the 450 Class, capturing his fifth straight victory at the series' last round from RedBud over the Independence Day holiday weekend. On Saturday, the second half of the season kicks-off from Dungey's home state of Minnesota for the Rockstar Energy Spring Creek National in Millville.

As the 2010 "Lucas Oil AMA Pro Motocross Championship" reaches the halfway point of the summer, MXSports Pro Racing is pleased to provide our stakeholders with an update on what has become the world's most prestigious and competitive motocross championship.

The 2010 tour marks the second year that the series has been under the management of MXSports Pro Racing and the second year for many historical improvements, including Saturday races, live television broadcasts, live internet streaming, and more.

All of these changes have been in conjunction with our commercial partners at AlliSports. By all accounts, these moves and many other smaller ones have succeeded in growing the series' reach. Virtually every single numerical category of measure is up, from event attendance to online viewership, television ratings, rider participation, ticket sales (both VIP and GA), and more.

Courtesy Red Bull: After weeks of carefully sculpting, polishing, and tweaking his YZ450F to make it sea and air-worthy, James Stewart finally tried his hand at the Red Bull Flugtag event on Saturday in Miami, Florida in front of more than 85,000 spectators.

James' confidence was soaring pretty high right before his flight: "Since I'm a Red Bull rider and can't actually be judged in the event, I figure I might as well just go ahead and break the distance record so that everyone remembers me" James said with a grin.

And, another star guest will be two-time World Motocross Champion Sébastien Tortelli, taking a short leave from his US-based 'ChampFactory Motocross School' and flying over for this occasion. Tortelli's presence offers a rare opportunity to see him in action again, and many fans undoubtedly will not have forgotten his 1998 MX2 World MX title after a heroic battle with Everts in Megalopolis (Greece).
