Dual Disk question - not how to

(1/2) > >>

burchy75:
I have a K1 here that I'm toying turning into some sort of CR750 rep (on a budget I might add - if this even possible) and wanted to ask a question about the caliper brackets.  I have the k1 fork lowers and K1 calipers and brackets but obviously the left side doesn't fit as it doesn't mirror the right side. I believe the K3 onwards caliper brackets could be used on both sides of the bike, is this correct?

I only ask as I have a perfectly good set of later forks that I may end up using instead of the K1 fork lowers if it's easier to get tot eh dual disk set up by using them and later caliper brackets.

Has anyone done a dual disk conversion on there K3 or older, can they confirm if this is indeed the case

Any help appreciated

Bryanj:
brackets will fit but need careful spacing

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...

I've just done my 550 and all I needed to do was use a spacer (washer) on the top fitting to the forks, I then used a gl1200 master cylinder and she now stops on a sixpence!

The modern pads are far superior to the originals. I was not looking forward to the brakes on my 750F but found they were actually very good compared to how they were back in 76. For a single disc single piston quite impressive really. Just wish I knew what they were.
