1150 3.5" wheel swap in a 700

[jwhelan65]

Same post here in my project thread http://www.thegsresources.com/_forum/showthread.php?t=209237&page=2

Thought I would share the mod:

86 GS 1150 3.5" wheel
86 GS 1150 Rear caliper
98 Bandit 1200 brake stay

This allows for a 150/70/17 to slide in with ease versus the 120 stock recommendation. I managed to barely squeeze a 130 in prior to this. As the photo shows below the Bandit stay is a direct bolt on with zero modifications needed. However I may have it shorten to straighten out the caliper for cosmetic reasons only.

The fatty..

The brake stay side with a full 1/4 inch of wiggle room, if desired I am pretty certain you could get a 160 in with no issues.

Chain side

Along with the new Hagon mono it should give it a whole new stance.

Looks Good

jwhelan65, what did you do, if anything, to get clearance on chain side?

Thanks.

I removed the chain guard, but actually I think it will clear with it on. The 70 sidewall measurement is a tad shorter tire which clears with all the stock spacing.

Understood. I am not familiar with the GS700 chain to tire spacing. Must be a lot more than the 1100E. I have an 1100EZ. Read posts of others putting the 3.5 / 17 out back. Seems spacers and 530 chain conversion almost always necessary even with a 130 / 90. Thinking therefore a 150 / 70 probably not possible without some serious chain offset.

Your GS looks great.

You shouldn't need any offset if you stay with a GS wheel. If my memory serves me correctly there members running 160-170 in the stock swinger.

Done..

I managed to get the same rear wheel on my 1100 Kat but I stayed with a 130/90*17 tire.
The brake stay had to be modified and an offset sprocket was used to clear the 530 chain from the tire

A Bandit brake stay bolts right up allowing the a 150..

I saw that
Good news because it wasn't easy to modify the original brake stay.
Interestingly enough my 130 tire actually measure 140 mm on a 3.5" rim

 

[jwhelan65]

Here is the Bandit stay, direct bolt in

[jwhelan65]

The b12 stay even has the proper bend to give you some wiggle room around the rear shocks on non mono set ups. Bolts in with zero modifications..

I have my B12 brake stay coming in the mail. Looks like this is going to be the key to an almost effortless rear rim swap. One thing needs to be said , if you are putting the 3.5" rim on a 83 750e you will need to put the 750 bearings in the 3.5"
