Well it didnt take long at all for the YFZ450R frame to fail. Given you can tell the quad was beeat on. My guess he cased the landing very very hard. Either way a frame should not break like this, maybe crack or bend but not break in 2 major places. Just goes to show CAST Aluminum is junk and always will be junk. Back to the drawing board for you Yamaha.
