What happened to all the cool bikes?

where did all the cool 80s and 90s  bikes go?  I went to the local big yearly bike meet on the weekend.  there was about 400 bikes there.  and apart from my small group of friends out of 400 bikes there was only 2 other 80s and 90s bikes.  eveything else was a dark bland color and looked like it was frim 2015 onwards.  why does this happen with bikes but not cars?  if i i go to a equivilant car meet. there is heaps of veriation and heaps of golden era stuff from the 80s and 90s.  What happned to all the bikes?  I can't think of a good reason for them to have all disappeared vs all the equivalent cars.   The bikes are just as reliable and easy to get parts for as the cars.  The cost is absolutely not an issue given the amount of brand new riders rolling around on brand new ninja 400s ect.  The bikes are also easier to store and work on the the equivilant cars.   Yet all the cars are still around and the bikes are nowhere to be found.
