Fits standard 28.6mm motorcycle handlebars and is secured with double sided mounting tape and zip ties. The tape prevents rotation and adds some vibration dampening. Uses 4 M3x16 bolts. You should be able to use any standard key to release the GPS but it may prevent casual thieves and accidental release.
Recommend 3m/Scotch outdoor mounting tape.
