I've been using the bike for more for commuting lately and less for off road shenanigans so I decided I needed some extra storage. I needed it to be both lockable and waterproof so I went with an aluminum diamond plate tool box. I used 3 U-bolts to securely attach it to the rack. When the lid is open they can easily be removed for off road fun. I've had it on for about a week now and its been great. Holds all my rain gear and keeps things dry. At first I didn't like it that much because its kinda big and bulky but its starting to grow on me the more I use it! Hope this helps if anyone was thinking about some storage options.
sorry for the crappy camera phone pics

 

cool...what size is it and how much does it weigh empty?

 

That's cool. I like that you painted it black.

 

It's HUGE! I'm assuming you can drop a helmet in there, as well as some extra fuel, a couple cases of beer... and maybe a kayak or two...

Seriously - nice work. I NEVER have enough storage space on mine...

 

Is that a GS or a KLX/s

 

The dimensions are 20in length x 10in wide x 9in height. Its lightweight aluminum and weighs around 7lbs empty

 

Nice work - thinking simple usually yields the best results. This is probably a much cheaper option too.
