STURGIS, S.D. (AP) — Never-before-seen crowds are expected to ride into western South Dakota this week for the 75th Sturgis Motorcycle Rally.

The rally officially kicks off Monday and is famous for bawdy behavior.

But authorities and bikers alike say there's no indication there will be violence among outlaw clubs like that seen in May in Waco, Texas, where a shootout involving bikers and police left nine dead and more injured.

Law enforcement agencies in Sturgis say they haven't received intelligence that outlaw gangs are planning violence as an extension of the Waco shootings.

A former Hells Angels chapter leader says it's likely the gangs will work to keep Sturgis mellow because of the attention on Waco.

Sturgis business owner Randy White says the rally is mostly a place for people to have fun.
