During last year’s Trans America Trail ride, the left side case of the BMW was packed with tools…99% of which we never used.
My buddy Glen carried more tools stuffed in a plastic tube that was bolted to the front down-tubes of the frame on his Kawasaki KLR650.
He had an extra one of these tubes kicking around in his “man cave”, so he gave to me to mount on the Suzuki for this year’s ride, but the exhaust passes in front of the frame on the bike so that location just doesn’t work.
Glen is a self proclaimed cheapskate. If there’s a cheaper or cheapest part or item out there, he’s bound to find it.
Now it’s fairly easy to find tool tubes designed specifically for a motorcycle for around $20 each (try the Tool Tube store).
And by the way, we also confirmed that the tool tube is just the right size to hold one of those small Primus fuel bottles found in camping supply stores.
At 12″ (31 cm) long with a 3.25″ (8.25 cm) diameter and a screw-on cap with a weatherproof gasket, the tool tube comes with a hefty mounting flange molded on to either end with three 5/16″ (8 mm) holes at the cover end and an elongated 5/16″ hole on the other end.
The holes are spaced 10.5″ (27 cm) apart, center to center.
Mounting the Tool Tubes
The tool tube (or tubes) can be mounted just about anywhere you can find the space on a motorcycle.
I had found some unused holes on the rear sub-frame on the sides of the rear fender of the Suzuki DR-Z400S, but they simply didn’t match up with the tool tube mounting flanges or fit the shape of the tube itself.
Then it hit me — how about a couple of straps across the IMMIX Racing rear luggage rack (review), bent to a 90-degree angle on the sides? I could then mount the tubes horizontally on either side of the rack.
There was enough room on the rack; the tool tubes wouldn’t obstruct the rear turn signals; they would be out of the way of just about anything else and if I mounted them with the caps forward, I’d be able to open up each tube even when the bike was loaded with luggage and gear.
I usually have some 1″ (25.4 mm) wide by 1/8″ (3 mm) thick aluminum flat stock laying around the garage, but wouldn’t you know it — the supply was used for another project.
So a quick run to the hardware store landed a 3 foot-long (0.9 meter) section and some stainless steel fasteners. Any leftover stock will certainly not go to waste…
I cut two pieces that were long enough to span the luggage rack and then extend down on either side equal the width of the mounting flanges on the tool tubes.
The straps were then bent at 90 degrees on each side in the vice by hand with a hammer tightening up the bends.
The rack already had elongated holes cut in the mounting plate, so it was a simple matter of marking and drilling four holes in the aluminum stock to match up with the plate.
With the holes drilled and some stainless steel screws securing the straps to the rack, the tool tubes were held in the desired position and marks made for the holes to mount the tubes to the strapping.
I drilled holes in the aluminum straps to match the mounting holes on the rack and the rough cut ends were rounded and smoothed off for a more finished look.
Both brackets were painted using black “Hammertone” spray paint, and it came out looking pretty close to the powder coating on the IMMIX Racing rack and doesn’t require a primer.
I used this same paint on the bracket for the Multi function volt meter (review) I installed on my BMW R 1150 GS several years ago and the finish is still holding up great, despite a fair amount of exposure to the elements and general abuse.
I then used some 5/16″ stainless steel button-head screws with nylon self locking nuts to fasten the tool tubes to the homemade brackets, along with some stainless steel fender washers against the tool tube mounting brackets to help spread the stress away from the holes.
For fun and added visibility, I cut out some reflective tape to make a pair of smiley faces and stuck them to the bottom of the tube which points to the rear.
These will “light up” when they’re illuminated by headlights and hopefully put a smile on someone’s face.
So there you have it — two tool tubes mounted on a pair of home-made brackets with a minimal of time and cost.
I asked my wife if she would make me a cloth tool roll and it slips nicely into one of the tool tubes.
With Glen as my adventure partner, perhaps I should reserve the other for First Aid supplies!
I also found some round plastic parts holders to hold spare hardware. I wrapped them in one of those “Absorber” cloths and stuffed it also inside the tool tube.
Having weather-tight storage for your tools and other items is often a must. If your bike doesn’t have any available space, a tool tube might just be what “the Doctor ordered”.
You may have to fabricate a bracket or a way to hold the tube on the bike…but then, that’s half the fun of “farkling”, right?
Whether you want to purchase them individually or in a “kit” that comes with a drill bit and the hardware is up to you.
Me? I have plenty of drill bits and a visit to the hardware store to rifle through their stainless steel hardware selection is always fun.
I paid $4.99 for each tool tube (plus shipping). A smaller tube is also available for $3.99; it’s 12.75″ (32 cm) long by 2.5″ (6 cm) in diameter.
From “M.S.” (July 2013): “May I suggest adding a large screw clamp or two to your tool kit. Looks like the Tool Tubes will be the first thing to hit if you go down. Usually brackets break first. A set of screw clamps could stand in for the broken brackets in an emergency.”
From “H.S.” (July 2013): “Looking at the pictures, I can’t tell how much, if at all, the tool tubes stick up above the rack. Do those still fit with the tail luggage you’re packing on the trip?
Other than that question, that install looks amazingly clean. I’ve heard of people using tubes like that before, but that’s definitely the cleanest looking install I’ve seen with them. Way to keep the farkling spirit going on that one.”
Editor’s Reply: I had this photo but didn’t add it, as it is nearly cut off at the top.
But it shows the tops of the tool tubes are about even with the top of the luggage rack. The height could be modified, depending on how far the aluminum bracket is bent. Chris said all of his luggage (stuff bags and a Rotopax gas can) will fit.
From “N” (April 2013): “Reportedly (meaning I haven’t tried it), the printing on the tube can be removed with carb cleaner.”
