So, I've been building little spacebikes based on this bike fairing part for a while, and by that I mean a couple years or something. IMO the motorcycle is terrible, ridiculously huge, but the fairing's good for little spacecraft. It was even used for this set 5969 prototype.
anyways, group shot
The Blacktron version's the definitive one.
and 100% legal legos, so I used it as a base for this instructions page
There's a bunch of others in my flickr gallery if anybody's bored and curious, cheers
