I say technology is killing racing. It has made it so expensive it can not support it self anymore .
Growing up, a factory racer often helped drive the box van.Yep, no tractor trailer(s) and posh Motorhomes..

In motocross, the box van contained two bikes, the race bike and a practice bike and a few consumable parts such as extra plastic fenders and tires. That was the race team, mechanic and rider. The van doubled as hotel for many. These were the Factory guys I am talking about. A privateer team today would overshadow those efforts.
Sought after sponsors might offer discount parts, a set of tires, free oil in exchange for plastering their stickers on every square inch of their bike, van, neighbors kid sting-ray.
At some point TV came and so did lure of getting real $$$. The competition ramped up in full public view. Riders now looked even more to technology to bring them an edge, better suspension, lighter rims, stronger parts that didn't break in the heat of battle.
Millions saw that trick stuff and demanded it for them selves. "I know I could cream that Hanna dude if I had his bike!"
The fall from grace had begun. Once, you bought a simple inexpensive bike. Whether dirt or road racing, you just pulled off the parts you didn't need or might break, zip tied on some plastic number plates and went racing!
Those days are long gone, you and I now ride on some pretty trick stuff as a result. We use tires that are better than the GP guys had just 10 years (less?)ago.
I love it! But also we are responsible for pricing racing out of reach, for suing manufactures of poor products that might break, for promotors of tracks I might crash on (while thinking I can beat Hanna). For demanding all the best components, teams of mechanics, Data engineers, suspension specialists, PR folks, trainers, the list goes on.
Basically, we have exceeded the $$$ taken in thru selling TV rights and dwindling sponsors that are no longer in the position to throw unlimited funds at the riders/teams.
Time to get back to basics?
