BMW R1200 GS Adventure LC (2014)

Bike Accessories

Looks great, and doesn't get in the way of anything.

Navigation

After taxes, and some blood, we fitted the Nav 5 for navigation on the bike. Mostly because, on the '14 GS Adv and various other R-models, it was made for it. The wonder wheel on the left grip and GPS prep package contributed to the easy sell. If not, the GPS prep does give you a nice little bar to clamp things to, but for the most part, having the Nav 5 (Garmin) up there is just convenient for going places.
In other news, I only use the Nav when I have no clue where I need to go, and for the most part it is a distraction. The display off function works very well to get your eyes back on the road.
Garmin's being what they are, Basecamp is a horrific experience and better suited for those who are technologically seasoned and can stand to learn a software from the 90's era. Mostly good for reviewing and importing tracks and managing waypoints. For me, its 50/50 on if the route I created in Basecamp is going to recalculate, and to see lower level roads or dirt roads, you have to zoom so far in its useless. My favorite trick is planning in Google maps, using gpsvisualizer (dot com) to converter that route into a track (.gpx) and then bringing that over in Basecamp. Then the damned thing recalculates the route anyways, so I usually just drive off of tracks and if I get to far off that's when we go to active routes.
The newer boxer engines get the added ability to display telemetry. This is fun, and you can zoom in to basically get your Trip 1 and Trip 2, or whatever data you need to be big and up front. For running roll charts or other data, this is probably better suited than the map screen. I typically like seeing Trip 1 and Range.
Cost wise, you're only another hundred out over the latest and greatest Zumo's, and the benefits of having telemetry, and an aesthetically pleasing device may drive your desires to buy it. Needless to say, I haven't regretted the cost, but one could do just fine with a ram mount cradle and a smartphone nowadays.

Handlebars & Controls

If you plan on standing at all, for any length of time, do this. Source - I'm 5'10". 40mm is the highest you can go without needing to re-route anything on a '14 GS Adventure. This is by far, the absolute best, and most necessary purchase for your adventure bike. Hands down, no contest. I would even skip the side-stand foot and get this first.
Also, once you get used to it, it'll just blow your mind how normal it feels. Other people may stare and their jaws may drop as they see the size of your rise, but pay no heed. Now, on that topic, of all the brands to choose from, I picked these as the most sensible ones. The price is right, the finish is good. The fitment is excellent. Only complaint is now the bars clamp with allen head bolts, so there's another bit to carry in the tool kit. Original clamp bolts were Torx.
Also, the rise causes some interference with the windshield, but ultimately, the rotation of the bars in the upward direction contributes to this as well, and there's nothing you can do other than put the windshield in the full up position or just deal with it. I think in one full day of off road riding, we went to full steering lock once. There is plenty of play in the windshield for this, and if you are seriously rigged for offroad, the windshield and mirrors come off anyways so its a non-event.

Lighting & Electrical

They look good. Not cheap feeling, very sturdy construction. Got a wiring harness, and cost includes the mounts (which were about 10-14$ per mount). They are out there for about $35 bucks a pair on Amazon.
They look great. Very conspicuous. Seen some guys with em on their trucks around town. They seem brighter than the stock LED headlight and Aux Lights in the official lit-garage eyeball lumen test, so overall I believe these would contribute to the light situation. I will update for another star once I run them at night and can comment further. Lastly, the mounts I bought are made by KC and are not very configurable. That being said, I cannot point these directly straight, they are pointed a few degrees inboard on either side.. (left one points right 3 degrees and the right one points left 3 degrees..) this makes a nice bright spot at 8-10'ft in the garage, but like I mentioned previously, will comment once I run them at night. 3.5 stars for price and construction.

Bike Protection

They look great! Fit an finish are good. Do they really work? Hard to say. I suppose, yes, if I were to throw a large rock up in there, these would deflect/absorb the impact and the rock would go away. Small rocks? probably nothing to worry.
On the other note, they do not impact the cooling performance of the machine at all.

Tires Wheels Brakes

I love these tires. They are very slow speed nimble, and track well on the highway at touring speed. Noise is low compared to the Anakee 3's. Some front tire whine is still present but not obtrusive. Grip is amazing. Both wet and dry, no issues. On dirt just as good. They feel more confidence inspiring in turns on dirt than the A3's. Now for the truth. There is a slight shimmy when running over poorly grooved pavement. I cannot tell for sure but I suspect it to be the rear tracking in the groove and causing a slight wander. Not an issue but some other ridersay be disturbed by this phenomenon. On grated bridges it is not bad at all, typical performance there. And it typically doesn't occur all the time, only in certain conditions.
