I was just waiting on someone to mention C-T. :rotflmao:  These boxes are rectangular, maybe turn it lengthwise to the wheel base? Also, this one may be different, but the bottom of mine is pretty flimsey. Gonna have a liner plate maybe out of 1/2" plywood?

I did a test fit with the box parallel to the wheelbase, doesn't fit very well, still too much overhang at the rear. There were some pieces left over from the cutting board I cut up for the base, used them to make plates for inside the box at the corners so that the box is sandwiched between the base and the plates. Seems pretty solid, time will tell.

Did a test ride today with the box filled with what I would take on a trip, 3 days clothes, toilteries, pair of shoes, pair of slippers, extra jacket, etc., contents weighed in at 25#....with the 8# that the box and frame weigh, a total of 33#, the box was not full, about 70%. Rode about 20 miles of local 2 lane at speeds up to 60, 15 miles of slab at 65-70. The bike reacts and handles normally, doesn't seem top heavy or unstable. There was a good breeze hitting me at about a 30 degree angle from the right, local TV reporting winds at 20-25mph, no ill handling effects noted. There was a bit of air swirling between me and the box, made my neck a bit cold as temp this afternoon is about 55. My hopes of actually using this thing are up.  ;D

I have trouble believing you will not hate that if you get in heavy cross winds for hours.  It will eat your tires up too.  How is it behind trucks at 70mph?

Can't be any worse than carrying a pillion, can it? At least it won't lean the wrong way when you least expect it.  :-[

The load can actually shift in a big box like that, if it's not snugged in there.

You are absolutely right. The only things that I plan to carry in the box is clothing, shoes, toiletry bag, etc., items that will fill the space and not shift from side to side or front to back. I'm not concerned if there is a bit of space between the load and the lid. My only real concern is that cross wind or turbulence from semis and the like might have a negative effect. I'm going to do a couple more short rides to test this out, including at least one with a smaller (shorter) box attached to see if there is a difference in the way the bike behaves.

Mr Bill, would you be kind enough to tell me the  flat surface dimensions (width and height) of your  cargo carrier.
I was doing some conservative  calculations on wind force and I am concerned . For example: A 2 ft x3 ft  flat  surface area at 60mph that would generate 55.3 lbs of force into the wind and  the vacuum behind it would be almost as great  resulting in over 100lbs of  rearward force. I understand  that the front surface is not directly in the wind but the rear flat surface is certainly creating a significant vacuum.

Mike.....Thanks for that input and your concern. The box is 26" long, 19" wide, 17"high.

If you need that much space a trailer would be a better option. I have a feeling that lid is going to catch air and lift off. It might make it easier to do wheelies.

But if you set it up right, it will lean into the corner with you.  Who needs to hang a knee out?

If you could rig up a remote-controlled hinge on the lid, you'd have access to some AWESOME aerodynamic braking!!

I tend to be a function over form type of guy. If this box works for ya, rock on.

I'm thinkin' a small rocking chair on top with a doll fixed up like Granny would be way cool. But maybe that's just me.

Mr Bill.  In direct wind at 60mph your wind force would be 32lbs and then add the  vacuum from the  lee side you may hit 50lbs. Not so bad as I might have thought.
It looks bigger in the picture then it really is. Take care.

No one has mentioned visibility. It seems as if this set up will limit the view behind, especially mounted perpendicular to the length of the bike. It has been ridden, how was the view to your six?

View is not obstructed, I can't see the box in the mirrors unless I lean my head out a bit, no difference than with a passenger on board.
