i'll see if i can find something better that this.
it is quite a change.
if u look close in this pic u may see where i cut the side cover. just below the frames shock gusset. i had to cut the edge of my side cover to fit the shock. the lower mount is not present in this photo. i was a dumb ass and cut it off. i thought the bike would sit lower if i moved back to the old mounts with the zrx shocks (since they r longer shocks). but in actual fact it did not. since the springs compress easier when layed down , the bike did not sit lower when the mounts were moved. all it did was make the springs toooo stiff. so i had to redo the mounts again.

Thanks Mark for posting the info in my thread.. I used a vac bleeder. I dont know if mushy is the correct description. It feels fine except the lever has to be squeezed further in than normal. It's working fine so I'm leaving that swap for later.
I'm waiting for all my parts to get here: cafe seat, Koso gauge, and zrx shocks. I need the seat and the shocks before I can chop my frame and bend up the top tube. It is great to have the help of such knowledgable people!

from what i see, u dont need my help. u already have the Master fabricator, Leon , at your beckon call.
just for others who may need to know, the top shock mount should be 15 5/8" up from the swingarm pivot, with the zrx shocks. this gives u the required angle to make the spring rate correct.
u mentioned getting a zx6 master cyl. just a note. it can be any master u think looks the coolest. all the newer 1's will work just fine. if u r mushy at the lever now, it may just be air in the lines still. i use a vacuum bleeder for all my bikes.even the old masters should feel firm.

send mark1122 a pm and ask him.he has been using zrx shocks for awhile and may be able to give some insight.

My koso gauge showed up last week. Unfortunately I had to send it back due to something on the inside of the lens. It should arrive late this week. I won a set of zrx1100 Kyb shocks off eBay. Do I need to change the rear geometry for these shocks? Since I am removing the top tube it would be a good time to move the upper shock mount if it's necessary.

As for the shocks, very hard to keep the donor geometry if i am to stay with the standard kz suspension angle. I used the zrx shocks with the standard kz mounts and they were extremely hard. But for sure they will be laid down. will send pictures.

Thanks for your help.

i did the same thing. i use the stock kz top shock mount and used a lay down bracket to move the bottom mount back. this gave me a lower rear stance. but the shocks were tooo stiff. so used the stock zrx arm bottom mount then i moved the top frame mount forward to copy the zrx geometry. it rides great now.

Adam, is that a stock brake for the triumph, or your own upgrade , it looks stock?
even the gp bikes only use single piston cals. i would think that baby is going to be touchy.

My options for now:

1- custom bracket for zx6 caliper ( Leon did terrific pivot custom bushing/spacers and shock mounts for this swingarm).

2- have an 96 zx9 wheel that might work with a zzr1200 caliper and hanger ( still experimenting).

3- The custom dual adapter caliper mount. (pricey)

u really dont want a dual piston on the back. u may find that it is to easy to lock up in the wet weather. i dont think any bikes have them?
i was wondering if u couldnt just rotate the bracket around so the cal sits near bottom. then weld on a tab to attach a brake arm, then cut off the other end ??
the best way would be as suggested, remake the bracket, but this may be more costly.
i'm sure Leon could give u a good price. He has satisfied a lot of guys on this site.

dont take that the wrong way, but I hear that Leon can satisfy the hardest men . :laugh:

the cbr 4f rear cal set up is very similar to what u have. i have an f4.

i have a zrx12 arm on my kz. it has a bottom mount cal with top mounted bleeders. i would not worry about the bleeder orentasion though, just bleed before mounting.if u change the cal u will def have to make a new bracket since the offset, bolt spacing, and axle size may differ.

when u mount the zrx shocks (or any shocks) try your best to duplicate the doners geometry. this will insure the spring rate it close.

I will have shock mounts welded on, i will try to use zrx shocks. How difficult was your monoshock setup ?

Can anyone here tell me about relocating the top shock mount on a '75 Z1 so I can get the shocks angled better, like a ZRX?????

Thanks Chris
