Where are all the bikes?

If I go onto olx, gumtree, autotrader.. the amount of bikes available is so limited. Where are all the secondhand bikes???

I'm just looking for a CBR250R, or 300R.. even a roadbike 500cc of any kind.. there is just no stock by the looks of it.

Then you just get the crazy guys coming out the woodwork, I saw a Kawa 300cc ninja, 8 years old with 22k on the clock advertised for R60k.. the guys have lost their minds, and there is nothing more kak than a Kawa 300cc. I just went to go look out of frustration.

At this rate I may just go for the Hero XPulse
