The short answer is: It depends on the mini van.
We’ve put this Yamaha Raptor 700R in a 2015 Dodge Caravan.
You will need to check your interior dimensions before attempting and you may need to remove the handlebars to make it fit. You’ll definitely needs something that has seats that fold into the floor.
You’ll definitely want to put a tarp down.
Unfortunately, most vehicle manufacturers aren’t that great at giving you usable interior dimensions. “Head room” usually means from the seat to the top of the vehicle, while “leg room” usually adds more height to that number, though it’s not often given.
All wrapped up and ready to travel.
And safely delivered.
