are you getting confused Garethmax, between clip ons and adjustable handle bars.
Clip ons have "sleeves" which clamp direct to the fork legs
adjustable handlebars have 5 bolted pieces which can be changed around a fair bit but are fixed to a clamp on the top yolk (original ones are marked Brevettato).
No non SFC Laverda had either type from new.
and helicopter jim means (I think) that US market SFC's of 74 vintage came with adjustable handlebars and not clip ons, but a lot of them got the clip ons at a later date, two batches of 50????? where the hell are they all then???
