Bought a few years ago and worked well on my tourer which had inaccessible tyre valves. New bike is naked so no problem with access, therefore surplus to requirements.
You will need a small piece of double sided foam to attach the holder to your bike (tank, dashboard etc).
This is a really neat little system. Reason I’m giving it away is that the pressure sensors that screw onto the valves have a battery in them, and I’m not sure how long they will last before needing replacement.
