What a great find. Ya gotta love those old race bikes and the guys who rode them.
I used to have a helmet like that in the 60s and sometimes wonder where it went. It was back when helmets weren't required in California but I had to get one to ride onto the Naval Training Center San Diego. The old helmet is long gone as is the old Yamaha I rode, and so is the NTC.
That there was terrific and I watched every second of it.
Best line - "They're off from the start and now funneling down like specks of sand in an hourglass into the first corner!"
Thanks for sharing this HISTORY!
