Rizoma Bar End Adapter MA600
Fits handlebars with a large thread inside - the inside of the handlebar is threaded
(your stock bar ends would have unscrewed from the handlebar)
MA600B is a double threaded piece of aluminium - it screws into the handlebar, and provides the correct size thread for the Bar End Screws.
All Rizoma Bar Ends are universal - adapters are required to fit them to your motorcycle
