Garmin Zumo GPS on KTM Duke 2
The Garmin Zumo is a weatherproof GPS that comes complete with a RAM mount kit for a motorcycle as well as a car mount. They were horrendously costly when introduced, but more reasonable prices can now be found if you look around. The best I could find was Pixmania. Via Amazon, it was £25 cheaper than direct from the store.
I tried the RAM mount on the Duke, bolted to the left handguard mount, and didn't like it at all. It might work OK on a Goldwing or big BMW tourer, but I couldn't find a position I was happy with, it was massive, and amplified vibration - of which the Duke has plenty - at the GPS.
I then thought I'd make a DIY mount, but after experimenting some decided that vibration was going to be a problem that was more trouble than it was worth to fix when Touratech already produced vibration-resistant mounts.
So unfortunately a better solution cost quite a lot of money.
What we have here is the Touratech Zumo locking mount, which has anti-vibration rubber isolator pads built into the platform. The lock, by the way, is just to stop someone walking off with the GPS whilst you're paying for fuel. It does away with Garmin's daft and losable tiny security screw, and is much more secure. The GPS cannot jump out of the mount in use when locked. It's a nice piece of kit, but not at all cheap.
The Touratech is designed to mount to a 12mm crossbar, as fitted to Renthal off road bars. Dukes don't have a crossbar. Touratech sell a bolt-on bar, but thanks to the handguards this was not going to fit.
Some web searching found the Gadget Guy, who makes a variety of ingenious kits to mount GPS units to bikes. Here, it is his basic kit, a couple of clamps that fit to the handlebar clamps via spacers and longer bolts. These attach a short crossbar to which the Touratech mounts. In fact Gadget Guy can also supply some nifty platforms that are much more compact that the Touratech, but as the Duke vibrates like a road drill, their lack of isolation seemed a bad idea on this bike.
The Gadget Guy kit had to be shipped from the USA as there is no UK source, but it's as nicely made as the Touratech mount, and good value for money even after paying shipping. More importantly it is a substantial improvement on the clunky, monstrous (but admittedly versatile) RAM system. I cut down the over-long crossbar to the exact width between the clamps for aesthetic reasons, but it all fitted nicely and is strong and secure.
Overall this is a great system, which does not obscure the instruments and is about as compact as possible whilst providing some hope of not being shaken to bits by the demented KTM single.
I am so far very impressed with the Zumo, its sensitivity, accuracy and ease of use are excellent and its mapping is almost always superior to the Tom Tom One I've. A couple of times previously the Tom Tom dumped me in wrong places thanks to bad postcode data.
I am a bit uncomfortable with all this hi-tech kit sprouting ostentatiously from the handlebar but after years of squinting at soggy maps in the rain, it's very practical. I just wish the Zumo was a bit slimmer. At over 1.5" thick it has to be one of the biggest lumps on the market. Why Garmin didn't put a belt loop on the carry case baffles me, as it's a big pocketful.
