John Maclaughlin was gifted or loaned one by Honda around 1960 after Honda quit racing it. Ed Kretz, Jr rode it at Willow Springs once. Ed started off, then there was a large cloud of dust at turn one. I asked him what happened and he laughed and said that it was faster than he thought - he entered turn one at about 130mph and didn't make it. Maybe ask John if he still has it. It would be a lot better than a recording.
