Well bugger me.
Put one of those cheeky start bids on a Aprilia RX50, spares or repair, runner, needs work but all there. Auction started at £400, I had bid and missed the reiju for that so figured what the hell. It spoke to me, stuck the flat bid on fully expecting it to go up. It didn't.
So I now have a Aprilia RX50 needing mild restoration, as far as I can tell that amounts to a mega clean and service. Picking it up Saturday.
Hope my instincts were good.
