The sport of Motocross became wildly popular in America in the 1970's, it has had some ups and downs over the years in popularity and participation over the years.
For the past 20 years there has been a decline in the number of participants and new bike sales are way down compared to the 1970's. This has been talked about for years and more recently is talked about daily among core fans of the sport in online forums, and all around the industry, it's a lot more fun to have more people that share your passion to ride with.
And as a racer its more fun to get 15th place on a gate of 40 riders than it is to get 2nd place on a gate of 5 riders, lately your more likely to find the latter at the grassroots level. It seems like new people are just not joining the sport anymore.
