Building a Samsung Galaxy S8+ Smartphone mount

Since I’ve bough a new phone that is waterproof, and fast enough to give me instructions via the GPS, I wanted to build a good custom mount for it.

There are waterproof cases including mounts for the S8+ on Ultimateaddons.com, should you want to buy a case for the bike. The prices of these are also good, but they are only for phones without a case. Thus bringing me to this idea.

I’ve had some styrene sheet laying around, and began mocking up the outline of the phone including the case.

This is what I came up with:

I painted it black, and wanted to test the quality of the work, which ultimatly failed by cracking the seam that holds the shade together.

Seeing this flaw in my design, but having already built a good platform, I began to improve it by adding another layer of styrene sheet to the original layers.
This needed some sanding to remove the seams between the glued pieces.

To reinforce it even more, I added some strips to the back side to cover those seams too.

As you can see, there is a hole in the back to put your finger through to remove the phone, because it’s locked in there tight, even without the charger attached to it.
The charging cable also doubles as a “lock” to keep the phone in place.
This works like a charm and is safer than just clamping it with a spring loaded clamp.

In the pictures above this text you can see how the charging port makes sure the phone doesn’t move.

Here you can see that I’ve added drain holes to remove unwanted water from the dock, should it get wet. I tested this in the sink, and it works perfectly to remove the water inside.
This should also work when the bike is parked outside without the phone in it.

The cradle has been painted to make it look a bit better, and now has been mounted to the bike.

In the last picture you can see that the phone can be placed in the mount in one way, so it could never fall out on accident. It is a friction mount, so no locking hardware is needed (except for the USB-C cable) to lock the phone in place.

A few remarks:
I have bought a China-made RAM mount (X-grip copy), and the only things that are usable are the RAM balls.
They are made of a cast rubber ball on a hard (composite/abs) base.

I wasn’t aware that the original RAM arms are made of metal, which means that the arm is prone to cracking if you tighten it too much. This happened, and I’ve bought a genuine RAM arm since, and that works like a charm!

Here’s a video explaining (almost) everything should you want to watch it:

Comparison: Givi D1111ST vs Honda Tall Windshield for Honda NC700X-750X

Now that I have multiple windshields for the NC700X I thought I would write a comparison between the two and see which one is the better one if you’re on a tight budget.

To begin with: I got the Givi D1111ST for free on my bike, and bought the Honda tall OEM windshield a week ago. “Why?” you might ask, is because the Givi D1111ST had a crack at one of the bolt holes, which I then proceeded to close up with superglue. That worked for a while, but then it cracked again.

Here’s a comparison by specifications:

Givi D1111STgivi-high-protection-windshield-16cm Honda Tall windscreen kithonda-touring-screen
Price (€) 81,65 (cheapest on RAD.EU) 149,00 (I bought mine for 79,71 at NC700shop.com)
Material Acrylic Polycarbonate
Height 49,5 cm 49,5 cm
Mounting Stock windscreen holes Aluminium rack
Looks Sporty, clean, black bottom Aggressive, rugged, clear bottom
Wind Protection Chest height Chest height

As you can see by the table, the height is the same, and the price difference is also noticable. I got my tall windshield cheaper at www.NC700shop.com but the original price is about 171€ (including shipping costs of 22€) which is a price difference from 89,35€.
For the price of 1 Honda tall windscreen, you can buy 2 Givi D1111ST windshields so to speak.

Both windschields work with the Givi HP1111 handprotectors.

Both have their problems and features:

Givi D1111ST Honda Tall windscreen kit
– Prone to cracking + Flexible
+ Cheaper – More expensive
– Uses original bolt holes + Aluminium rack
+ Adjustable using the original bolt holes – Needs modifications to change height
+ Doesn’t yellow overtime – Yellows
+ Scratch resistant – Scratches more easily
+ Wider – Narrow
– No vibration protection + Grommets to resist vibration damage
– Thin + Thicker windshield

Both have their pros and cons, but for me, the reason to buy a tall windscreen from Honda is the aluminium rack to add a GPS mount, and the more flexible windshield.

Polycarbonate windshields are more flexible than acrylic ones, and are also stronger, but not more rigid. To hold their form, they need to have a good bend in it to add some structural integrity.
Acrylic windshields on the other hand are UV and more scratch resistant than polycarbonate windhields. They do however shatter or crack on impact.

The Honda Tall windshield kit has a flaw, and that is that when mounting a windshield extension, it tends to bend in the wind. A solution for this is to add 2 spacers to the upper bolts, bending the windshield and adding structural integrity. However it is more durable than the Givi D1111ST.

Here’s a video of the Install and test ride with the Honda Tall Windschield.

Test ride:
There is a lot more different than just the wind protection.

Because of the wider opening on the bottom of the windshield, it makes a vacuum and removes almost all turbulence. It is however not “all away”. I used a windscreen extension to compare it to the Givi one, and it does feel better. (note: the givi windscreen is also tested with windscreen spoiler).

My findings are (for a guy of 5ft7, 1m72) it feels much better, AND I can reach higher speeds more easily without hiding behind the windshield.

The Honda windshield does wobble more at high speeds, but that isn’t such a big problem.

Final verdict:
I like how much difference in wind protection there is, even when the windshields almost have the same dimensions.

The aluminium rack on the Honda Tall Windscreen has the advantage of being more sturdy, but the Givi one has the advantage of being relatively cheaper compared to the original price of €140,-

The clear winner is the Honda Tall Windscreen with the rack, unbreakableness, rugged look, and the wind protection.
