My large Duratool top case project

I do a lot of two-up multi-day touring, and it’s always a struggle finding a place to put all our gear (especially if we plan on camping), even though we’re both pretty disciplined when it comes to packing. I decided to make a sort of a “tour pack” for those sorts of trips that would give me more room. I’ve never really liked the bulbous Givi style top cases, plus they (and the big square top cases) make it more difficult for my significant other to get on and off the bike. I already use the large size Duratool cases as panniers, so I figured I’d get another one and make that into a top case. However, knowing that there is a tendency to overload a top case when you have more room, I knew I wanted an additional support system so the stock plastic rack support wouldn’t get overloaded. I didn’t want to attach anything permanent to the bike, though, so this is what I came up with. The aluminum support arms carry some of the load down to the crossbar on the HT racks, so the stock luggage rack support and rear frame don’t support the full weight of the top case. To remove the case, all you have to do is pull the two quick release pins and flip the quick release lever, and the case comes off. The support arms can stay on the bike when the case is off, but they come off with just a spin of the knobs when the tour is done and it’s time to remove the tour pack. The support arms then store in the case when it’s not being used. When you take it off, there is no hardware left behind on the top rack or the side racks.


The case is very solid when its on the bike. It’s nice to have the extra room, and the case is big enough to hold bigger items like my tent, so I don’t have to strap it to the outside of the bike. It’s only about an inch and a half higher than my usual top case, so my SO can still get on and off the bike in her usual way.

Feel free to use or adapt the idea to your own gear. Here is a link to my photo album that has more pictures: http://www.yamahasupertenere.com/index.php?action=media;sa=album;in=83

If you're interested, here is a link to my homemade pannier quick release system, designed to work with Happy Trail racks. I have it set up with Duratool cases, but it would work just as well with Pelicans, or even aluminum panniers. Just loosen one knob on the outside of the case, and the whole case comes off.

Hey RCinNC, I was wondering where you have been...............just got my answer, another fine piece of ingenuity.
One question though, how is the stability with the box overhanging to that extent? In as much as front end wobble on the highway?

Hi Dogdaze, and thanks.

I test rode it with some weight in it, both on the interstate and in town, and I didn't notice any stability issues. I think it's better to have the load spread out laterally like it is with the Duratool case, rather than using one of the narrower higher cases. Even with those I think you'd need a lot of weight back there to really affect the handling. I don't plan on putting more than 20-25 pounds back there; it's mainly for the bulkier items like the thermal liners for our gear, our rain gear, a tent, etc.

Like the extra support and use of pit pins!

Thanks guys, I appreciate the feedback! I might design a pack tray next for the rear deck, so I can safely lash down something bulky like a fuel can for those long trips...

For anyone who has followed this thread, I had a chance to do some more extensive riding with the big top case. I took a two day, 580 mile trip through North Carolina and Virgina using the new top case, loaded with about 20 pounds of stuff. The ride included both interstate and lots of twisty mountain roads, including the switchbacked gravel road that crosses the mountain into Burkes Garden, VA. The big case worked out great, even on the low speed switchbacks. No balance issues, no weird turbulence issues on the highway, and none of the components came loose. I think I can call this a successful project.

Seriously? I have yet to see anything you have done NOT work! Nice report RCinNC, but not one I'm about to try, I will be waiting for you to make the fuel tank mount though ::008::

LOL Dogdaze, there have definitely been some failures in execution. The GPS mount worked fine until I switched to a Garmin Nuvi, where the power cord sticks out of the rear of the unit. Nothing short of a redesign of the mount would make it work successfully. It can be done, but at the moment I just can't face a third rebuild LOL.

I'm still playing around with a pack tray idea. It's in the "sketching ideas on a legal pad" stage.

You are my "Pack Mule" Master!

I'm a bungee cord pig.
You are a load analysis engineer.

LOL Snakebitten, my ability to be an engineer is severely hampered by my pretty abysmal math skills. As for the bungee cord pig thing, a friend and I once transported an upright piano in the back of a Ford Ranger with a grand total of one bungee cord securing it. You'd be amazed at how many chords a piano can play all at once when you drive off a 6 inch high curb and the piano floats briefly in the air before it crashes back into the pickup truck bed....

The completionist in me wouldn't let me finish this project until I added one final thing; some pin retention cables, in case one of the pins works itself loose.

NOW it's finished.

Um...well, maybe some footman's loops on the lid for tying stuff down......or maybe a built in light so the case lights up in the dark so you can find things.....

I wonder if there's a 12 step program to cure me of this......
