Having seen the link to the sat nave mount here I went and had a look and took the plunge, although a little on the steep side for a bit of metalwork I must say I was mightily impressed with the quality and fit when it arrived. I favour the Powerbronze double bubble screen as it really takes the wind to a smooth flow when set in one of the middle settings for my six feet three height.
The Sat Nave mount fitted perfectly and although it came with 4 new screws of slightly longer length than the Kawasaki originals they had very weakly defined hex heads and slipped a bit with the Allen key, so I went back to the better quality Kawasaki hex headed screws that fitted fine and covered the depth needed with no difficulties.
This now left me with the original Kawasaki satnav mount which I have now been able to add my universal waterproof phone case mount to so if I want to use Calimoto anytime i don't need to drag out the tank bag to slide in the top. Win Win and now I'm triple screening! Who needed to look at the road anyway?
