Howdy again. As usual, when I install a new piece of equipment, I have this irrational desire to document the process, in hopes of making it easier for anyone who wants to do the same install in the future. I generally take more pictures than are absolutely necessary, but I figure too many is better than too few.
This time, I’m installing an SW-Motech vibration-damped GPS mount
on my ’09 DL-650A. A couple of complicating factors: 1) I’ve already got the Madstad windscreen brackets
(and want to keep them) and 2) my new zümo 660 GPS unit needs a special adapter
to fit with this mount.
Right, then. Let’s roll up our sleeves, crack open another bottle of malted assembly lubricant, and get to it.
First, assemble the mount per the Motech instructions. I didn’t document that too much, as their instructions are pretty clear. I suppose you could assemble it after it’s mounted on the bike, but it’s much easier to do on your workbench/kitchen table without the fear of dropping some tiny screw down into the bowels of the motorcycle (foreshadowing alert
Anyway, here’s the mount and the cradle all put together.
Oh, remember how I mentioned the special adapter? It looks like this:

It’s really just four Delrin spacers and some longer screws. The Garmin cradle for the zümo 660 (and the 665) sticks out on the bottom, so it won’t mount flat against the Motech mounting plate. The spacers stand it far enough away so that the lower lip is out of the way. You’ll need four washers and the little nylock nuts from the bag of hardware that came with the zümo. Here’s a close-up of where the spacers go.
Alternately, if you don’t want to spend ten bucks for the adapter kit, you could try grinding a few millimeters off the bottom edge of the Motech mounting plate, but then you’d be getting dangerously close to the mounting holes. I suppose you could also use a stack of washers, but you’ll still need the longer screws. The adapter kit is easier.
Here’s a look at the “vibration-damping” section of the mount. There are rubber bushings incorporated in the mount to help ease the shakes. More on that later.
Here’s the whole thing. That’s the big fat cable trailing off from the bottom-right.
Ah, the cable. The other (non-cradle) end of the cable presents us with a bouquet of connectors: audio in, headset, power, and a cute little mini-USB for the traffic antenna. There’s even a handy in-line fuse holder, complete with 2A fuse.
We’re going to chop them all off.
Why would you do such a thing, after Garmin went to all that trouble? Well, I know I’m not going to get the traffic receiver. And any other audio needs can be accommodated via the built-in Bluetooth. I thought about trying to bag or tape up the connectors so I could leave them in place, but in the end I figured it’s much easier just to lop ‘em all off.
(Hey, Garmin – if you’re reading this, how about making a zümo cradle that only has power connectors, without all the other stuff? I know the car cradle is power-only, but it won’t attach to the Motech mount)
I put the bracket roughly in position and trailed the cable down the outside of the bike to gauge where I should make the cut. It ended up being about 12” from the big cable-splitting point.
There’s enough left over that I could conceivably put everything back together should I go insane at some point.
Strip back a couple of inches of insulation and you’re rewarded with a lovely multicolored spray of little tiny wires.
We really only need the power wires. Fortunately, they’re wrapped in foil all by themselves (as opposed to the braided sheathing that’s also in there). And they’re the biggest wires in there, so look for the slightly-bigger pair of red and black wires among the tiny forest. They’re on the left in this picture.
I snipped off all the other wires at slightly different lengths (to avoid shorting) then added heat-shrink tubing and a few wraps of electrical tape to (hopefully) waterproof everything.
will sell you a lovely little waterproof quick-disconnect set to extend your zümo power cable for $20 or so. It’s probably the most affordable thing in the entire Touratech catalog.
But since I don’t really plan on doing a lot of disconnecting, I just used Posi-Locks. If I need to pull the cradle for some reason, it’s easy enough to undo (and re-do) the Posi-Locks.
I put a little strip of black electrical tape on the negative connector so I could keep them straight.
When I measured my cable-cutting point, I wanted it to be in roughly the same place at the big electrical connector down in the lower part of the left fairing. That seemed to make the most sense, so if you ever needed to take the bike apart, you’d see the Posi-Locks and take them apart at the same time as the big connector.
I measured out some red and black 18-AWG wire and twisted it together, connected it to the Posi-Locks, then zip-tied it to the big cable that goes aft toward the battery. I have an FZ-1 Fuzeblock
mounted back in the under-seat tray, and made the final electrical connection there. Fortunately, the 2A fuse that came with the Garmin is the right mini-ATM size, so in it went.
And we’re finished with the electrical.
