Hi everybody,

Does anyone know if the fork legs from a 750 (inverted) can be used in a 1989 1100 clamps?

Will the wheel & brakes fit?

Cheers.

Straight answer is no. 750 inverted fork leg at the clamp measure 5xmm (50 or 52?) and the 89 1100 right side up forks were 4xmm (43 pretty sure?). Therefore not a straight fit and then you are modding pieces to fit wheels brakes below.

Try and locate the inverted forks clamps and all will bolt in as an assembly. Putting the 750 forks in there will change the 1100 steering figures as those 750 forks are a little shorter than the 1100 and can only be slid down so much.

Thank you. I did a pretty good search, including the interchange sticky, but could not get around the right info.

I´ll try to look for a set... if at all.


Does the inverted fork work much better than the "standard" fork, or does it provide any advantage (in addition to the looks)?

the front wheel and calipers will work, but the forks, triple clamps, bars and fender will be different/required.

if you have fairings, it's best to buy the 1990-1998 gsxr 1100 upside/inverted front-end, since the handle bars are mounted above the triple clamps, whereas, the 750's handle bars are mounted underneath the top triple clamp. otherwise, the handle bars will hit the fairing.

Thank you!

I managed to find some 1990 inverted forks and the triple clamps. I guess these are the ones you referred to right?

Will my ´89 wheels & brakes (& the rest of the bike) work with these?

Thank you!

I need help, please. Can someone confirm if these 1100 1990 forks will fit my 1989 1100 bike?

They are quite cheap, and I´ll lose them if I don´t give a fast reply.

Thank u!

yes, those 1100 forks will work on your 89 1100, but like ghostrider mentioned, you will also need a complete set of triple clamps, handle bars, front fender, and front axle (your axle will work, but it is a bit shorter).

it's best to buy a complete set, or just begin buying the parts separately.

your 89 1100 stock front end should be fine, unless you are really pushing/racing, or are having issues/problems. USD front ends do make a handling improvement, especially compared to the stock first gens (41mm forks, no real adjustments and 18inch wheels), which is why i converted all of my first gen 750's to USD front ends.

here is a recent foto of one of my first gen 750's, when i was fitting a new front tire. it's best to buy a complete front-end. the 750 and 1100 triple clamps are different and NOT interchange-able.

Well ive seen a 86 with a 07 front end on it, what im most concerned about is its geometry as im not too hip on bike stuff. Going to measure frame width today to see if the 07 swingarm can even fit. These new parts are damn light :banana

Took me a while, but I finally managed to find a complete front set.

I believe this will be direct fit into my 1989 1100. Do you agree?

Thank you!

i can't open your link, but the forks appear to be from an 1100. the important thing is that the bars are mounted above the top triple clamps.

Thank you. Yep, seems like the link died. The forks come from a ´92 1100, and have, as you say, the handlebars mounted on top of the upper triple clamp.

I got them today on the post. Seem massive in terms of width, and look awesome.

Of course, I´ll get new steering bearings. Are the USD forks bearings the same as the "regular" fork bearings?

Cheers!

yes, all of the oil-cooled steering stem bearings are the same. buena suerte.
Thank you @86gixxxer Just ordered them from All Balls. Will post (hopefully better) pics of the process.

Hello !
Reading your thread with great interest. I have an 86 750, and a set of either 92 or 93 1100 forks in the shop. Have you been able to get this all together?

I built a KZ 900, and the Gixxer shown in the photo with lots of help from a good friend who lived next door. after about ten years of fiddling I got tired of building and sold the KZ. The Gixxer was built by my neighbor with my help, he generously gave me the bike 2 years ago. It has been in cold storage for a few years, and I think I am ready to start up on it again.

Any tips you can give are appreciated, 17" wheels from which bike are and easy swap for instance?

Building bikes is easy, building them correctly? ... Not so much... lots of time to get things just right.

nice fist gen you have there. i spy some high bars, SS headers and custom oil lines.

USD front end swaps have been done many times. where are you located? post a foto of the forks in question, or start another thread to get responses. this site seems to be dormant.
