Super solid mount replacing handle bar bolt. Minimal vibration, wonderfully effective and simple.
I put one of these on each handlebar of my K1600GLT after taking off the existing smaller ball and replacing it with a 1" RAM bolt through ball. Works very well, solid as a rock compared to the other types of mounting options.
Well worth the price, even after buying the RAM part.
Worked perfectly with my K1600 GTL
Tackform is by far the highest quality product available for your phone mount with all metal parts construction unlike any other brand out there.
