This video shows a group of people racing on dirt bikes around a track. The riders are wearing helmets and are riding closely together. The track is made of dirt and has several turns. The riders are leaning into the turns and kicking up dirt as they go. The video is shot from the side of the track, and the riders are moving at a high speed. The video is shot in slow motion, which allows us to see the details of the riders' movements and the dirt being kicked up by the bikes.
