I stumbled across this video when looking at MrNotWrong's thread on alternatives to pop rivets and the first thing I thought was, this could be the start to an Optimus Prime Costume. The problem is it seems a little small for adult size and I'm not sure what Yamaha vehicle this comes from. Does anyone recognize it?
