I've seen sportbikes fit in the Chevy Astro Minivan (actually, it was my 954 alongside an RGV250) without taking off any parts. No double bubbles though.

I've also seen a gixxer fit in a Honday Odyssey, but I can't remember if he took off the windscreen.
The cool thing about hauling in a van is you won't attract unwanted attention at the hotel when traveling to the track and you don't have to haul all your **** in every night!
