Having just pawed through my collection of 1981 and 82 Australian Two Wheels magazines it turns out that no Katanas (750 or 1100) raced in the 1981 Castrol 6 Hour. The race was held in October and in that months magazine is an article on the first available road test of the 1100 demonstrator.
In none of the magazines is there any mention of spoked wheel 750 Katanas.
