A beautiful reproduction of the original Honda clamp, that should bolt on to all early Z50 and CT70. Please check your own parts book to be sure.  This is the last version as fitted to 70cc, with extra notches to allow locking of handlebars up or down.  Retrofits to 50cc without issue. 

This part is NLA from Honda. This clamp has the correct OEM type metal inserts and a nice mirror polish. Included with our handlebar holder two pieces of nicely chromed handlebar nuts.

According to the Honda website the handlebar holder fits 25 different models as detailed below. 

We will answer questions promptly, thanks for looking.
