My one ever roadkill[0] on a motorcycle in some 400Mm, and even that one was second-hand.
It swooped across the road, got hit by an oncoming van first with a glancing blow which resulted in some rather cartoonesque saltos that landed him right ahead of my front wheel, probably dead already.
[0] Not counting the 23.7 trillion midges that ended up on every bit of frontal area after a summer night's ride across the Markermeerdijk. You don't want to close your visor because it'll be totally plastered over in green goo in mere seconds, and you don't want to open it either.
