Further thoughts on the Seige article (which are partially redundant thanks to 247's and Firko's posts that went up while I've been typing).
I'd say that 80~90% of people
get involved in VMX to enjoy the bikes they owned or aspired to, in their own personal "Golden Era" - there are variations, but its typically our mid-late teens to early twenties, on bikes that were new or nearly new at the time.
I'd estimate that 5~10% get involved simply because dad races VMX, and they tag along.
Only once people are involved in the sport, do they start seriously considering bikes from 'out of their era' - and it's surprisingly easy to get people onto older era bikes, particularly one or two eras older than 'their era'.
But the number of people who jump straight into an older eras is tiny. If we are counting on them to sustain the sport into the future, the older eras of the sport are doomed.
Look at the rider demographics of VMX in its boom days: hugely biased toward riders about forty years old, on bikes that were about twenty years old.
Nowdays, the demographic is biased toward blokes about 50 years old with the most popular class being for bike that are about 30 years old...
It's no coincidence that 50-30=20 and 40-20=20...

The boom times of VMX were when the sport appealed most to riders who were in their mid-thirties to mid-forties. It stands to reason: it's the group who are most likely to have the income/family/mortgage pressures under control, and still be fit/energetic enough to want to go racing.
The relatively new Retro MX/Northern Districts (pre-90) club here in NSW supports this - the median age is about ten years younger than Heaven's.
40 minus 20 still equals 20.

It might seem odd, but all of the above seems to add up to one thing to me: to ensure the longer term health of the older classes, we need to embrace the newer era classes.
A serious, renewed publicity drive (outside of the VMX world) will be a huge help for VMX generally, including the older eras, but the long term health of those older eras is dependent on the strength of the newer VMX classes.
