Continuity mistake: When the Wild Hogs first go to the Delfuego Bar, it is a bright sunny day and the ground is completely dry. When Woody had to go back and recover Dudley's bike the ground is completely wet, but when Woody is riding Dudley's bike back to the other Wild Hogs, the ground is again dry.
Factual error: At the 28 minute mark, the Wild Hogs cross the Taos River Gorge Bridge in Taos, New Mexico. Shortly after the scene with the skinny dipping, they drive down the road and at the 34 minute mark, the sign on the right says, 'Missouri State Lane.' I never knew Missouri was inside the state of New Mexico.
Continuity mistake: During the brawl at Maggies Cafe the blinds in the 2 windows left of the entrance appear and disappear a couple of times.

Audio problem: When Damien Blade shows up at the end, he shows up on a motorcycle close to the crowd, right on the main road, yet there's no sounds of a motorcycle pulling up before hand. They would definitely have noticed him pull up and hear his motorcycle coming in way before he stepped off the bike and the crowd parted way.
Factual error: The vulture following Dudley is a Lappet-Faced Vulture native to the Sinai. One would not encounter one in New Mexico.
Continuity mistake: When Dudley is thrown through the window of the diner, the window is shattered. In the next scene, the window is back without being broken, then in the next scene, it is broken again.

Continuity mistake: During the final fight scene in Madrid, Doug is pushed through the white fence next to the restaurant and the next scene showing the fence, it's completely fixed.
Continuity mistake: When the family arrives at the swimming hole Dudley is to the right of Woody. In the next shot Dudley is behind and left of Woody.
Plot hole: When they are swimming and before the family shows up, the Wild Hogs throw all their clothes on to the side of the pool. When the family gets in and they get caught, the mom seems to see the clothes from across the pool but she is looking the opposite way of where the clothes should be.
Deliberate mistake: In the scene where the Wild Hogs are driving past the bikers' bar, Woody uses his throttle hand to show the bikers his middle finger, yet the bike is still able to accelerate.
