    There are no straight bolt on ones that are any better than the 1980.

    You can bolt on a set of Kawasaki Calipers with GS550 disks or CBR Disks with some adapters...

    Do a search, there is a lot of info on the Kawasaki Mod.

        Even those have an adapter bracket... Are they off the shelf? Are they opposed piston? If not I wonder what gain they'd give over stock.

        Cool discs what brand are they...

            Salty, I don't really know what brand the discs are. I bought it this way. The brakes are Lockheed racing brakes. The bike was converted new in 1978 to an AMA racer in California and put back to street upon retirement.

            I will say that these brakes are absolutely great! One finger operation, you have to really get used to them because they are probably 5 times stronger than my 83 1100.

            FirstTimer was working on a similar conversion when he found a set of Lockheed on EBAY.

              I suspect they are opposed piston (essentially the same design as 1150 front brakes). The disk looks much bigger too so that will help a lot.

                Yeah you can still get the lockheeds from the factory, but i haven't found the disks yet. Thinking about contacting Kosman for rotors once i get the rest of my bike finished up. They seem to do custom stuff. I know about the CBR stuff but would like to stick to period rotors like the Wiz. I think the disks the wiz has are old brembo rotors.

                  Have a set of GS550 rotors ground down to 5mm & heavily drilled... that would be one way.
                  Wonder what diameter those are?

                      330mm that would be one reason they're more powerful...

                      You guys might be interested in these if you have deep pockets.........

                        The Kosman discs look great. I just checked my pockets, they aren't that deep.

                          It's stories like these that make me feel lucky. I stumbled across a barely used Works shock for $150, Yosh Stainless Duplex for $150, PFM iron rotors for $160 a pair. These PFM rotors seem to be something different than they show in catalogue. Mine are drilled instead of slotted like they offer now.
