gs750 suspension conversion

The answers to the front end GSXR USD can be found here:http://www.suzuki-katana.com/katana_suspension.html

That is meant for katanas, would it apply to my 78 gs?

As I suggested earlier, you can check the bearings used on the triples for both models on the allbearings site.
The GS 1000 and 11000 Katana are the same size.

So, I need 954 triples (top and bottom) + up to 1996 GSXR 750 front end?

The GS1000 top bearings match up but the bottoms do not:

GS750:
Top: 25 id 48 od 13 width
Bottom: 27 id 48 od 14 width

GS1000:
Top: 25 id 48 od 13 width
Bottom: 30 id 48 od 12 width

CBR954:
Top: 26 id 48 od 14 width
Bottom: 30 id 48 od 12 width

Maybe RC51 forks in 954 triples? RC51 seems to be a common swap for the 954 guys.

It would seem to me that an eleven liter Kat would be WAY bigger than a 1 liter GS!

I see no problem in fitting a GS 1000 stem with it's own bearings in a GS 750 frame as the outside diameter of the bearings are identical
I read an article a couple of years ago in a British magazine about a GS 750 with a GSXR G/H fork.
To me it should be a simple drop in for the GSXR 1100 K ( RSU) triples in the GS 750 frame ( except the lock stops of course) as I've used both types of forks on my GS 1000/1100's.
Else you can go for the USD GSXR forks with 954 triples as stated.

You caught me on that one

How would the 954 triples fit though? or is there enough of a gap in the steering stem that the bigger stem (by 3mm) on the 954 would fit?

Unless it is a case of turning down the 954 stem and using GS sized bearings?


Would 2004/05 GSXR 600/750 forks fit? Here is some specs on them, the top and bottom triple spacing lines up I am just worried about the spacing between the forks as I could not find any info on the 954/929 triples (was told they are the same)

IIRC the top triple for 954/929 is the same as the 2nd gen GSXR so you can mix upper and lowers. Not sure if it is GSXR 750 or 1100. Katman would know for sure.

Alright thanks, so just so I am 100%, the 929 and 954 triples are the same but I should use 90-95 gsxr 750 or up to 98 gsxr 1100 forks and rim/brakes etc?

Yes it is possible to fit a 2004+ gsxr forks by changing out the bearings and mounting the whole front end.

Use the search feature "titles only" and search words like your title "suspension conversion","front end swap" etc.. You will find lots good info.

[silverbullet132]

So if I got 30x48x13 top 30x48x14 bottom bearings + an 04 gsxr 1000 front end, it would slot in?

Anyone happen to know if the stem is long enough for my 78 gs? The GSXR stem length is approx 260mm. Could not find any info online about the GS stem length.

Sorry I may have posted a bit hastily as
I'm not sure if the stem lengths are exactly the same. I'm not familiar with the 78. I just want to let you know others have mounted 2004 and newer, like in this thread... A 2008 gsxr front end on a 1980 1000 frame.
be aware that the newer forks are shorter and can cause ground clearance issues and the handling can be effected changing the trail.

Yep it'll drop right in, the bearings from All Balls will come out to about $55 plus shipping.

Thanks, I will assume the 04 1000 fork has the same stem length as I remember the 1000 forks/stem being a straight swap (am I wrong on this?).

Any chance you have the part #s I need to slot in the 03-04 GSXR 1000 front end?
