That pipe is the old style of "fatty" head pipe. It was the way they added as much expansion chamber as they could without changing the design of the frame. Once they figured out that a frame redesign was worth it for the extra power then the pipes got HUGE like a modern 2 stroke's headpipe.

Here's a fine example from yamaha's history:
