Right then, just had a chat with TFTuned and it turns out the 2003 Z1 drop offs i bought off ebay are oem and therefore are classed as 'bastard forks', but having looked at them and a set of Z1FRs that i have they look to be externally identical.

So does anyone have a pair of 2003 Z1FRs knocking about that are broken in a non-internal way (damaged stanchions/crown) that i could cannibalise?
