Ultimateaddons Motorcycle Handelbar Clamp Attachment - 3 Prong Adaptor

This is one of our most popular 25mm motorcycle mounting attachments.  This attachment offers a very neat and tidy solution for mounting a range of devices to your motorcycles handlers. This motorcycle attachment is designed to replace one of the existing handlebar clamp bolts to allow a range of devices to be attached to a motorcycle / scooter. 

If you ride a motorcycle and have limited space on your handlebars replacing one of the clamp bolts is an ideal solution.

This attachment requires you to remove one of your existing handlebar clamp bolts.  Once you have removed the bolt, measure the thread diameter and the length of the thread that goes into the handlebar.  

We offer three sizes of bolts 

  • M6 = 6mm 
  • M8 = 8mm 
  • M10 = 10mm 

The second measurement is the length of the bolt the supplied bolt lengths are approx: 55/60/65mm, once you attach the 1" ball attachment to the screw head the thread length that will go into the handlebars are approx: 27/32/37mm.

Whats in the box

  • 3 x Bolt Lengths
  • 1 x 25mm/1'' Ball Attachement
  • 1 x 3 Prong Adapter


  • Simply remove your existing handlebar clamp bolt.  Select the closest size bolt (remember bolt needs to be longer) and place the bolt through the 25mm ball head.
  • Tighten till secure with Allen Key, also check the other handlebar clamp bolts are secure.     


  • The 25mm / 1" ball head connection gives you a wide scope of mounting options. We offer a wide range of 25mm adapters to allow users to connect to a range of devices.


  • The Ultimateaddons 3" extender has been designed to allow you to raise the mounting point higher and to give your more freedom on positioning. This 3 inch extender can be used on any 25mm 1" ball head mounting attachment.
  • This extender is really useful when used in conjunction with the handlebar clamp bolt attachment, this extender will lift the mounting point approximately 3" making it easier to see and better for positioning (especially when using a tank bag).
