Hi

got to get cake stand back before the wife comes home
Not tried yet but hopefully sorted

Hi all
A couple of questions regarding the brake disc on the CB500 Four K1:
Has anyone purchased one of the remanufactured discs (manufactured using modern materials, giving a far superior brake than the original.)  from DS ?
If yes, did you feel an improvement riding in dry and wet conditions 
It’s the only part I’ve not replaced on my brakes, but still feel they could be improved without going down the twin disc route.
Thanks in advance
Pat.
