What happen to Dave? This place is like a wheelchair rest home for cripes sake. IN bed already? Maybe the bed pan needed to get dumped.

I'll have a go because it's been sitting for a while, I'm reasonably sure it's an Aprilia Mana 850, check the link above.
Someone else take it away if you think I'm correct, normally it's up to the photo poster to answer but Dave's in bed just now.
