An Astro van has a lot of space. What kind of van do you have? I moved my XB9R in an 94 Olds Silhouette, had to angle it and the front tire was pushed up into the back of the drivers seat but it made 350 miles no problem.
When I took my test, I had to haul mine to DMV, and took it in my horse trailer. It made it easy. Just rode it up the ramp secured it, and put the ramp up.
Once broke down in a town 40 minutes from home, had a friends brother that lived there, he drove a PT cruiser, we hauled the bike home in the back of that, im sure you can manage a van.
I really try to refrain from making blast comments bec I've seen some cool bobbers and cafe racers. But a minivan too. You are killing me. To answer the real question anything will fit it just depends how dedicated you are. Get out the tape measure.
