1947
The Motocross des Nations motocross race is an annual "team" event, where riders representing their country meet at what is billed as the "Olympics of Motocross". The event has been staged since 1947.
It is actually called the motocross of nations now. Look it up on the internet. They do have a movie called 60 years and a day about the 2008 motocross of nations.
Great Britain
Daytona Supercross, Motocross Des Nations, Glen Helen, Budds Creek and Unadilla are all major events.
America with Tim Ferry, Ryan Villapoto, and Ricky Carmichael
I don't know that it is the most important race ever, but what stands out in my mind is the 1981 Motocross DES Nations where Team USA won completely unexpectedly and brought on a 13 year domination of the MX Des Nations by a country, up til then, considered to be inferior in motocross. daytona supercross is always the best race and atlanta 2009 supercross is the best race in history
