Revved-up engines, dusty leather, elaborate tattoos and cold beer come together for a wild time at The World's Largest Biker Bar as truTV heads to Sturgis, S.D., for a fourth season of the hit series Full Throttle Saloon. Premiering Wednesday, December 19th, at 9PM (ET/PT), Full Throttle Saloon looks at the behind-the-scenes havoc at Michael Ballard's enormous, 30-acre indoor/outdoor watering hole during one of the biggest biker rallies in the world.

Each year, The Throttle has nine days to generate enough cash to cover its 300 employees, 100 of which are voluptuous go-go dancing bartenders. The expansive venue features large and small performance stages, a burn-out pit, a tattoo parlor, a wrestling ring, restaurants, dozens of stores, hundreds of cabins for rent and parking for the thousands of bikers who come to town for the annual motorcycle fest.

Ballard's business partner, Jesse James Dupree commented:"This is the ultimate destination for people who love badass motorcycles, kick-ass rock and roll, beautiful women and a cold belly washer.”

Dupree is most known for his role as the chainsaw wielding frontman for hard rock band JACKYL. In addition to touring and performing in front of thousands of fans all year long, the bands performance during the rally is always one of the biggest highlights complete with Dupree's desire to always exceed the level of excitement brought from the previous year. He has set the bar high for his antics this season seeing as his last few antics include successfully having himself shot clear across the crowd from a cannon.

Last year, Ballard and his crew turned up the heat to create the biggest season yet of Full Throttle Saloon. With the economy down and everyone else in Sturgis cutting back, Ballard decided to take a gamble by actually raising the level of events at The Throttle. With a cadre of new and even hotter female bartenders, new managers and new events, including one night featuring six different bands, he thought he had it made. But nothing's ever easy when it comes to running a place like The Throttle.

This year, fireworks will erupt among Angie and the girls when Michael announces he will not let Flaunt perform at the rally. Fajita Mike will return and start a rivalry with the new hibachi chef next door. And Jesse will make a big money commitment that puts a wrench in Michael and Angie's secret post-rally plans.

truTV's Full Throttle Saloon premiered in November 2009. The show scored 2.1 million viewers and 1.2 million adults 18-49 in season three, making it the season its best yet. Full Throttle Saloon consistently ranked among the Top 5 ad-supported cable programs in its Wednesday timeslot with both adult and male demos, climbing to #1 in the timeslot among adults 18-49 for its third-season finale.
