For the first time in Monster Energy Supercross history, four titles will be awarded at the season finale in Las Vegas, including the Supercross class, Eastern/Western Regional Supercross Lites and Dave Coombs Sr. East/West Shootout titles.

While the biggest names of the Supercross class lay it all on the line on Saturday night, the rising stars of the Supercross Lites class will determine the respective eastern and western regional champions for the first time ever inside Sam Boyd Stadium.

The ultra-competitive Supercross Lites Western Regional Championship took another dramatic turn in Salt Lake City as GEICO Honda’s Eli Tomac captured his second-career win in what has been an impressive rookie season.

Now, the title fight is closer than ever with Monster Energy/Pro Circuit/Kawasaki’s Broc Tickle, who finished third in Salt Lake City, holding just a two-point lead over his rookie rival.

As a result, whichever rider finishes ahead of the other will likely be crowned with his first-career championship.

After a two-race break, the Supercross Lites Eastern Regional Championship will also bring its 2011 season to a close in Las Vegas.

With three wins and a podium result in all eight races so far this season, GEICO Honda’s Justin Barcia sits 20 points ahead of Monster Energy/Pro Circuit/Kawasaki’s Dean Wilson.

The up-and-coming riders have been the class of the field throughout the season and like their west region counterparts, one of these riders will leave Sam Boyd Stadium with his first-career title.

Following the final main events for each respective region, the 20 fastest Supercross Lites class riders in the country will go head-to-head for pride and prestige in the annual Dave Coombs Sr. East/West Shootout.

The one-of-a-kind race is the lone opportunity for fans and riders to determine which young star stands amongst the rest via an intense 10-lap battle.
