Welded in 16 mm x 1.5 mm threaded insert
accepts factory bar end weight.
Australia & Europe: Some FZ1(N)aked models have a 6mm threaded
hole for the bar end weight.
When you install the new bar, first check the fit of the bar end weights.
They should thread all the way into the new bar by hand.
A bad thread on
the bar end weight will damage the thread inside the handlebar.
