An early morning fire has destroyed a popular Sturgis saloon that billed itself as the "world's largest biker bar."

Crews from the Sturgis Volunteer Fire Department responded to the Full Throttle Saloon on South Dakota Highway 34 about 12:30 a.m. Tuesday and found heavy smoke coming from the building.

Sturgis Assistant Fire Chief Shawn Barrows says firefighters tried to get inside but heat and smoke forced them to battle the blaze from the outside. The building was completely on the ground by 3 a.m.

Barrows says there were no injuries.

The bar, which featured such amenities as zip lines, musical stages and rental cabins, had been the subject of a reality television series.

The cause of the fire remains under investigation.
