When it comes to Harley Stunts, there is no bigger name than the Unknown Riders. With a smoke filled, loud and in your face stunt show, no other team gathers a crowd like this trio. While the guys do their thing on the ground, the FMX riders pull tricks in the air leaving the crowds unsure where to look. Talk about sensory overload. All this was one of the main attractions at the 2015 Sturgis City Park events.
