This is the best tool for mounting your smartphone on your motorbike.
I have one of these on my Africa Twin in Europe. Without a doubt, its one of the best accessories I’ve come across for riding. It places your smartphone anywhere you’d like it (I clamp mine to the handlebar), with easy viewing access to your Google Map directions. It can be easily repositioned and it swivels so you can adjust your phone out of direct sunlight or rain. These are awesome! Check out the normal sized Ram Tough Claw X-Grip here, or the plus sized version for larger phones here.
And, the best waterproof USB charger.
