Non-Championship Grand Prix Motorcycle Races, has anyone got any links to information on these.

Have a patient trawl through the racingmemo.free.fr site, also bike70.com should be of interest....but other posters will no doubt have more....

I’m not sure which races count and which don’t, and are you primarily thinking of 500cc events?
The Motocourse annual used to include details of some of these. So far I have looked at 1979, but it doesn’t have anything for races outside of Britain in that year -- non-championship 500cc Internationals:
