Hello Eric .
I expect that you are aware that B S A made a light chassis I recon with a narrow rim that it might suite a super.. Just a thought .
To bring a little mirth to you all as a youth my ride to work outfit was a d1 Bantam I used the front half of a gents cycle frame to make the chassis and a wheel from a Itom moped , It was the most evil handling beast that ever I have ridden to witness my then boss 6FT3″ Don Chisholm driving it was unbelievable .Regards D F.
