Just brought an 05 Bandit motor home to put in a 91 750 frame for a street fighter project!

Hey Y'all! 

Greetings from Georgia, USA! 

So, I've had a very clean 91 gsxr750 frame and 93 swing arm hanging around the garage for awhile and I have been plotting to build a tire smoking wheelie machine for fun. My first race bike back in `90 was a gsxr1100K, so there is some sentimental value here. I found a used bandit 1200 motor on E bay and just picked it up today from the freight terminal. 

Very excited. 

I've been trying to find a comprehensive parts interchangeability guide, which I swear I've seen here before. I'd like to put a newer lighter, radial braked frontend on it, plus newer, lighter wheels. I like the late 2000's stuff, but I need some specs. 

Any help from you lovely people would be helpful.

The fork chart is knocking about in the vault somewhere. 
In all seriousness, I would just buy the front end you want and make it fit. Worst case scenario you’ll need a slingshot stem to be swapped into the bottom yoke and a little machining in the top yoke. Get your measuring tape out and go try it

.... for the front end swap you can use the  “ all balls racing”  website fork swap  guide.....

Thanks guys!

Good points all round

Hey y'all , just in case someone is following, I've put a `94 750 swingarm on the bike , but I'm having issues getting the shock to fit. I'm using an 06 gsxr 1000 shock, having heard and read it's a direct bolt on...  I've tried several different pivot links, and it seems I should be using the M, or `91 link. 

Any insights?

 

[xracerfranz]

Oh, specifically, it doesn't seem the the link to bottom mount is going to work. 

[Captn]

Link to the frame ears or shock to link, or link to swingarm?

I have fitted a ZX6R B1h front end on my slabby. Bit of mucking about with head bearings, but apart from that, no problem.

Bottom link to lower shock mount. I had another answer from a member that recommended shaving some material from the top shock mount to allow some movement. I'm beginning to think i may just get a stock shock to use in the interim until I find a nice aftermarket unit in the future. There was no donor bike in this build.

I ended up finding a `94 750 frontend, the blue one and decided that would be the way to go. It would probably qualify as the best that came on  gsxr's up until `94-`95. 

Maybe i'll upgrade down the road.  this was an easy fit, using the `91 lower tree.

@xracerfranzI have 2 1100 lower links that I can measure for you. If they'll work we'll figure something out.  I'll snap a pic with measurements when I get home this afternoon. 

[Captn]

@xracerfranzBTW one of them is a M link and the other is off of a W.

Thanks! It's tricky since I used the braced `94 arm with the `91 frame...

[Captn]

@xracerfranzI usually 1100 N frames and use 750 N swingers and 750 or 1100 shocks. Never had an issue with the bottom shock mount to link area. Your braced swinger is a bit different though.  Hopefully one of these links will line up.

[xracerfranz]

Something I noticed when looking at someones 1100 build (of the same year) is the upper shock mount is part of the frame, and seems to put the shock in a more vertical position. I want to be careful and not screw up the handling on this bike. I had a bmw s1000 shock which is considered a drop in mod for `91's, but since I used the braced arm from the `94, it buggered that idea. The reservoir on the shock hit the swingarm. I will have to use dogbones from a `94-95 as the ones from the 91 don't fit.

Ugh. So much hassle just because I wanted a braced arm. I've never done much the easy way... 

[Captn]

Good info there.  I was thinking about the braced swinger as well.  Not now. 

[xracerfranz]

Well, from what I see, if you have an 1100 frame the swap my be better, although the swingarm is two inches shorter!

Thanks. The 93 and 94 pivots were a bit short, the 91 was a little longer. I can't help but think a spacer on the top shock mount to frame interface might solve the clearance issues.  I just don't want to screw up the handling...
