My brother's old pictures from his 1962ish days in the Japan Airbase motorcycle club. I'll update as I learn. He told me they were invited to drag race at Hondas test strip. I remember him saying it was only a couple yards wide.
Edit: 1 and 2 seem to be the same pic. I'm working as an old guy on a new scanner. I saved 6 pictures but every time, it saved #1 I'll work on it again when I get home.
