these kyb forks are 43 mm with disc brake mounting points and disc cover mounting points ,they are alloy not mag i know most of honda showa's were mag , have seen a set of the kyb 38mm factory forks Johnny0 and they look a bit like them , they are quite expensive, so i hope they fit , but ive been looking fo a long time for hrc factory forks or fox forks to fit the 84 with no luck so the kyb's will do
