this is brilliant stuff. http://motorbikearchives.com/Video-Gallery/High-Resolution/1964-Motocross-des-Nations.html
you can recognize names Like Tibblin, Smith, Lampkin, Persson, Rickman bros, Geboers very very cool vid. Bikes are amazing. The track is super-natural and check the hills for 3 in suspension!!
great find robertaccio, what a great year to be born. Funny how sandy the course was back then, I raced there in 1990 and it was hard pack, I really remember those down hill drop offs.
Thanks for the link Robertaccio! I found it interesting how the leaders were jumping into the downhill section. Others were just riding down it. Very good website. WR Bob
