Thanks for the reply! The bikes are 86" long and the bars are 33" wide. I'm not worried about fitting them side x side because i can always face one forward, and one backward and the bars won't interfere with each other. But from all of the pictures I've seen, people have fit their bikes in by putting the front wheel between the 2 front seats, to gain a couple more inches. I would need to put the bikes behind the seats and still be able to have enough room to close the doors.How long is a full size dirt bike and how wide at the bar ends?
