I guess bikes that appeared near the end of a model life sometimes went through a cycle of:
Sat in a showroom, waiting to sell.
Passed by, when they didn't really meet the requirements of the time

(i.e when today's 40-50 year olds were that age, would we want a K100? I wanted an RC30 or 1000EXUP)
Still there, as a conversation point, slightly out of date. New model is out. Plenty available used. Not fashionable.
Still there, something quite unusual, not worth much so adds more value as a conversation piece than it would to sell.
Still there; "Never gonna sell it!" the odd punter remarks that 'That'll be worth summit one day'.
Still there; nostalgia effect starts to increase interest… "I used to have one of them, it was great!" Becomes a bit of a punter (of a certain age) attractant.
Still there; the people that were too young to afford one back in the day, or were old enough to get, enjoy and then sell one back in the day, now have disposable income…
Bang! it's suddenly worth selling. And someone has invented Ebay for rabid nostalgists. Yay!
