GS 750 Single to dual front disc brakes

[Dizzixx]

I will add in below with *** as it's easier.

If you PM me your email I can send you a list of compatibles that I have pulled off here over the years.

Is Is there a meaningful difference between the concourse and tokiko calipers? Or between the different rotor options other than installation? (ie - cost to replace, durability, trackability, etc etc)

Does someone know the actual master piston size on the EX650, EX600, EX250 etc?

So I finally got around to working through most of this. I swapped the triples and the rebuilt a dual rotor pair of forks. Note these are not the inline axle but instead a leading axles pair.... which leads me to my next question. Does anyone know what other hardware I need? It would appear I need a longer axle bolt, possible some different shims and spacers? Also I cant seem to figure out why but somehow my triples/axle ended up crooked...?



Yes the bars are pointed straight but the wheel is pointing off the the left... but the top and bottom of the triple line up and I have no problems installing the fork tubes....
Also has anyone else done this and do you know what to do with the speedo? Is there a different housing as the only way I could fit my old one was pointing straight down



The whole point of this clusterf*** was to get the salty monk brake mod installed. I noticed today when test fitting everything that the caliper mounting pattern on the leading axle forms is longer (bolt to bolt) and set lower (ie - closer to the ground) than the inline axle forks, this of course means that the salty monk brackets I bought A) do not fit the lower fork tubes, and B) even if I reproduced them with the roughly 8mm extra pattern spacing on the upper corner bolt hole they would not place the caliper in the correct position..... omg what a mess!

Anyone have the geometry of the different setups if I wanted to produce a custom set of brackets?

Any ideas on how to sort this out?

The rotor & caliper combine are much lighter than stock as the inner spider is Aluminum.....

TKent has a Blackbird rotor which is 310mm but there is a 900RR rotor that is 320mm that should be better suited. I don't know the year 900RR but I know it exists because I bought one by accident years ago (the guy told me it was a 295mm rotor..).

EBC & MetalGear have a new 320mm rotor. Its for a Honda Bros, which wasn’t very widely sold. I looked & didn’t find any used.

I bought the EBC MD1124LS for my T500 cafe build. Am just starting on the project so it will be quite a while before I have any updates on how it worked out.

FYI: I am currently using 95 zx600 callipers and master with 07 vfr 800 rotors I picked these based off of the list of compatible parts sent to me by salty monk

I would guess that since the forks installed into the triples with no problem then your left fork is bent. As far as you gauge goes, you could fabricate a bracket to change the angle.

Well I will have to pull the forks and take them into work and see if they really are bent. Regardless as it turns out, Dan aka "Salty Monk" was able to confirm that in fact the conversion is not currently compatible with the leading axle forks (so I totally ground off the steering stops for nothing!)

So I am in the market for a set of inline axle forks both with caliper mounting locations. If anyone has a set of these for a 750 they are looking to sell please let me know. I would also be willing to trade as I will now have two other sets of forks I will need to get rid of, the original set of inline axle forks for a single caliper setup (maybe for someone doing a smaller bike modification?) and also now these leading axle forks which have a brand new set of seals and have been thorough cleaned out inside...
