 Yep, it's always been my dream, turn a BSA Gold Star into a chopper. Improve the looks 100% as well as gaining the improvements in handling...  and...  brak...ing... errr... never mind.
Found in a presumably shortlived Swedish chopper magazine Ride & Glide from 1985. I guess the biggest question is why the %$#@! was this in my old magazine collection? I can't see myself running out to pull this off my local newsstands shelf.
