Watch Gymkhana Drifting Motorcycle Mayhem [w/video]

Move over Ken Block, as these stunt riders have put together one heck of a killer Gymkhana video of their very own... with motorcycles?!

These speed freaks are a French stunt team called the Switch Riders and they've put together one of the most memorable, tire-smoking drift videos ever seen on 2-wheels. Riders Jérémy Mérirès, Thomas Sagnier and Kevin Parussini throw down just over 4 minutes of amazing motorcycle mayhem, as this viral video continues to spread like wildfire online.

Their super sweet riding and outrageous stunts on this closed course are carefully paired with top-notch film quality and video editing, delivering a wicked video we had to watch twice. Keep in mind these dudes are pros, so please don't try this at home with your buddies and a few GoPro cameras.
