1987 GSXR 750 fork. performance mods.

[Guest]

Hi, beside blanking off the antidive on the forks, is there any internal mods that actually work on the damper rods or such. And ive heard different triple trees work better for handling. Are the 1100 and 750 trees same offset? Thanks

Sharpy, 1st gen 750's and 1100' s have the same fork diameter but the offset on the triple clamps s different. I'll have to check but if I remember correctly, 750's have less offset than 1100's

Coool these are 750. Thinkn i read somewhere from Kat they where diff, thanks. I know the discs are same as the 88 1100, and 88 1100 wheels 3 spoke are rare but I got the 6 spoke ones with a 4.00 x 18 rear. That will do for now.

Any other suggestions?

I installed these forks on my own GS 1000 ST.
One cannot just block off the antidive as oil must still be allowed to go through.

I bought an adapter from Canada that fitted perfectly.

I got some RaceTech emulators and springs in there as well.
One thing I never quite clarified is the diameter of the disks?
The 750 has 300 mm disks while the 1100's had 310 mm disks but I don't know if the stanchions are identical with different calipers or is it vice-versa?

Thanks heaps John, Lots easier when one can pick another persons brain. And seems there 1100 forks . The inner tubes are 596mm long compared to the 750's 580mm and the electronic antidive was only on the 1100 and 750RR and discs are 310mm. But you got me on the outer tubes and calipers. Both have different part numbers in the book. Any one have offset measurements for the 750 top triple tree clamp please. Even if you just measure the spacing between this spot be awesome. Thanks

I have the GSXR 1100 streetbike kit from ABM on my bike: http://www.krax-moto.com/13177-te-st...00-suzuki.html
The offset is difficult to measure with great accuracy but I found 33 mm?
I would be surprised to find a different offset for the GSXR 750?
The ABM PN's are different for the two bikes but it could come from the positionning of the ignition key?

PS: the offset on the GSXR 1100 K 43 mm RSU is 35 mm and on the R6 43 mm RSU is 40 mm...
