Old wheel swap comfirmed

[Guest]

Is there a monoshock version of this that will work with something like a GS750?
(Don?t have anything in particular in mind. Just thinking about the next build while I spend big $$$ on the current builds.)

Bandit 1200 G1 or G2. Need bushings for the pivot bolt, and shock mounts welded on. I have a 190 on but a 180 would be more sane....
Bandit G2 rim as well

Interesting.
The Suzuki two strokes I?ve worked on all had swing arm bushings. Knew about the GS-series update to needle bearings.


Looked at the online parts diagram for a ?78 GS750B & a ?97 GSF1200S. The GSF has bushings & needle bearings.
Are those bushings bronze or steel?
Is there a forum topic that details this conversion?

Bushings in GS are steel.

You need to duplicate the GSF bushings except with a 16mm hole instead of a 20mm one, and make the lip about 2mm wider. I think I have a modified bushing here somewhere, I'll see if I can find it and post pics. I know I needed a 3/8 offset sprocket and the Bandit hub for proper spacing.
Rob Wilton had a kit to do this, not sure if he is still selling them, he had some health issues. http://www.parts.suzuki-katana.com/

If rob is no longer selling these, I have a set that I could measure so they can be reproduced. Are you sure one needs a Bandit hub? I was told to use a GS1100 hub, but that doesn't fit properly. That would explain why I have a no fit issue.

YMMV. I used a 3/8 offset sprocket and the Bandit hub worked best with one washer under the sprocket. Rob's sprocket was a custom, IIRC 12MM offset. I used a 190 tire and it really is too big. A 180 should have more fiddle room. With a 190 the chain is a few MM away from hitting multiple places although it hasn't been a problem so far. The chainguard was nearly impossible, had to do major shock clearance. Not pretty, but it got past tech inspection. I started with a Bandit guard.
