Maybe I could get there by stripping pieces and parts off of perfectly good motorcycles. That’s OK, I’ll do without.
Why am I being so harsh?
Because you took a vital structural part and reduced its thickness and therefore strength. Doing it without knowing how much difference that will make is one thing. What makes it worse is you did this to a hidden area, where it won’t be apparent to the next owner. The only way they will know is if you tell them. Maybe you plan to do that. Maybe you will drop dead tomorrow and the bike will be sold by someone else.
Start trimming on the steering knuckles of a 35 year old car, then go on a car forum and ask opinions. See how well that goes over.
And this was all done as part of making the motorcycle look different to meet a style fad. Well, that makes it all worth it.

Since you want tires based on “that old cafe look” rather than performance, I’m not sure if you’ll find the info you want here.

is the tire thing a trick question? why wouldn't whatever size tire that came on the gsxr fit the gsxr rim? there must be a zillion tires for that bike. you aren't looking for a tire to fit an old k bike, you are looking for a gsxr tire. or did i miss something?

I want an old style cafe tire fitted onto a modern rim, I was told this cannot be done and had no explanation why.If by old style you mean narrow, one reason might be the Gixxer rims are too wide for narrow tire beads to seat securely on them. The Gixxer is designed with radials in mind—wide ones, especially the rear tire. An additional reason might be the diameter of old style tires tends to be greater than Gixxer rims.
The early K model tires look more like the BSA and Triumph tires of yore.

I thought that the wheel rim was too shallow to take the tire to seal onto but they are exactly the same, the GSXR rim is slightly wider but still do not understand why this will be a problem as tires can stretch or get a slightly wider tire.There is data available that a uni-educated person should have found before now even using a clapped-out Mac in need of an upgrade it can't support.
Here's a table (http://kawtriple.com/mraxl/tire_rim.htm) that shows minimum to maximum rim width for sizes of tires. This isn't the only table on the Web but its color caught my eye. Gixxers have rims typically 1.5 inches or more than the maximum width for narrow tires, despite what you might think. Although these tires might have been called balloon tires when they had tubes in an earlier and simpler motorcycle age, they are not balloons.

@Max, I looking over the internet and it seems that the ZX7R front end will fit with the original ZX7R Triple and triple top. The length of the stem is about the same. So you will be on the safe side in that case. Furthermore google around, several guys have done the R1 fork and a GIXXER750 front swap and left some nice details and information.
Hope you will figure it out before I do so I can take your notes as well :)
Cheers and best luck,
Nick

Also look at the tire size you have on the GSXR wheel you have. The GSXR wheel isn't that unusual. If it's say a 180/55-17, then you look for tires the same size to start. - 17 being the wheel diameter. 180 is the section width in mm and the 55 is the sidewall height as a percentage of the width. Therefore you could look for all available tires at that size. You could look at 190 wide perhaps. Maybe a 60 sidewall...Depends on the look and what is available.

Google is your friend if you like computers and the Internet. I don't! Infact I hate computers because I cannot see how they work. Trial and error and having the balls to give things a go is what I find works but thank you for all the constructive comments. The thing that got me was being told the GSXR wheel cannot take the tire but without any explanation why?
The pic is the Firestone classics I want to buy in a 17" tire. I'm sure they will work but only way to know is to try. If not I have other bikes I can put them on, it's only money.

I’m planning to change the controls also, so I will buy a brembo master and clutch set this winter when I do the USD fork swap.
Regarding the K1100 brake cylinder, i’m using one now on my k75 and it works like a charm bro!
Here is a picture.
I used the throttle cable of the k1100 with a custom braket on the k75 throttle body.

I'm going for the ZX9R or ZX7R fork, this is interchangeable and also the BWM K rims will go in easy with the stock Nissin callipers.
Good luck, looking forward on your end result.

The tire issue has been solved by running a 110/70/17 on the GSXR rim and a 140/60/17 on the k1100 rim. I know I could have gone to a 160 on the rear but you will gain much more in height than you would width because of the narrow rim and this would change the geometry even more. In reality the bike has been lowered a total of 46.6 mm front and back with the the aid of the adjustable rear shock, not ideal but best I can get it, the test will be in the ride. I am interested to see how this effects the side stand issue too, should help if any thing and better than attaching a big block on the end of it.
I have also upgraded the rear disk and pads to brembo as the front now has 6 pots. Side exit exhaust fitted and just the electrics and hook up the koso dl-03sr speedo to work out.
NickHeljman thanks for the offer on mastercylinder bro but I'm going to buy the k1100rs master new, I have gone this far with it and can't cheap out now.

Regarding the rotors I worked out if I used a k1100 rs front wheel as the spindle size is the same, rotor dimensions are 300mm then did some reading into what Suzuki runs a 300mm rotor. The closest I could find was a 305 rotor on a Suzuki ( can't remember which ) this would mean there would be a difference in cercumfrance of 2.5 mm and would mean I would have to purchase another set of calipers, as well as the k1100 wheel and disks. You just need to look to find what will work for your set up and then get a master cylinder to fit, but then in changing the mastercylinder you also will need to change the controls,throttle etc.
What I am looking into now is a BMW r1100s front wheel, the spindle size is smaller but wonder if I can press bigger I/d bearings into it to fit the larger spindle. Disk rotors are the same 320mm as the Suzuki so it should work.
Post by: NickHeijman on October 16, 2018, 03:35:05 PM
Go for a nice black look on the lower and upper triple. I'm sure it will looks amazing on it.
How did you end up with the break callipers ?
I have the ZX7R fork ready now. Bearings just arrived OD 52 ID 34 H12mm Need to grind the stem down 1mm and make 2 rings of 4mm to cover the 12mm height of the bearings to the 16mm height in the frame.
Needed to make 2 spacers to fit the stock K75 rim in. Rest is fits like a glove.
Looking forward to see your master cylinder and all on the bike !

.
So I have put the R1100s wheel on stop For the time being and sticking with the GSXR wheel, disks and callipers. The mastercylinder arrived today as well as the throttle housing, I went for a k100rs 16v as its a 20mm bore and can use my original switchgear. The draw back is I also needed to buy a brake leaver and brake switch and throttle cable as they are all different to the 8v. I had to modify the throttle cable as there was just not enough adjustment on the throttle to take up the slack, added a small spacer ( pics attached ) and works like a dream. It's all coming together nicely, should be finished just in time for winter 👉😞
