I remember converting my 550 to dual disk back in the early 80’s... i used the same parts as on the original setup as the forks were already drilled... so in other words a mirrored set up, it was a 1978 model and I was able to re-assemble the parts as a mirrored assembly. All i remember was being very dissapointed as there seemed to be little if any improvement in performance. I dont think those old single piston calipers are much kop and thats one thing I'm not looking forward to experiencing again when i get my 750k4 on the road. Maybe modern pads make a difference these days...
