Astro Van. Two bikes will will fit easily. Best budget racebike hauler every. Cheap parts, easy to work on.
Yep, definitely Astro. Have had two of them, best bet is 2003-2005 with the larger and 4-wheel disc brakes, 16" wheels. At the most, if you have a tall windscreen you have to lean the bike over a little while loading.
An old buddy of mine, Alex Dydula, used to ride his bike up a 2x10 board into his pickup. When the bike got on the bed the rear tire would spit the board off the tailgate. Took balls, and awesome throttle control. I never had the balls to try anything like that. I used two ramps, and walked the bike up.
I rode a ZX-9R (the mid-90s, heaviest kind) into the back of a U-Haul truck once. Once. Scariest thing I ever did on a motorcycle.
modern stow & go type mini van (2007+) can handle a sportbike IF you remove the wind screen (all size bubbles!!) Roughly 46" or so through the back. If you roll in through the side door... alot easier. 52''+.
