160 tire using oem hub?

[Guest]

Im looking at purchasing a 4.5" rim and using the oem hub. Goal is to use a 160/60/17 tire... Has anyone done something similar?

I figure it can be done with offsetting the front/rear sprockets and using a narrower chain... help/insight much appreciated!

Nice!
I should have mentioned that my project is a 78' GS1000 with wire wheels.....

Yes, it can be done. Our race GS1000 uses a 4.5in rim and 160 rubber. A 520 chain helps - with this we only neded a 3mm spacer behind the front sprocket.
The 5 - blade cush layout is common across many Suzukis, I found one wider than we needed and machined it back to get the chain line right.

That's awesome news thank you, don't happen to remember what the donner was for the cush?

Cant help with the set up you want but i did the maths for the smaller 1st Gen Gsxr wheel (4inch)

I have the same setup on my 1000, I used a gs 500 Cush drive and machined it down I believe 3/16” If I remember correctly

Great tool for doing wheel offsets.

Awesome! Thanks!

Thanks. Stay tuned for me sorting out the GS spoked hub into GS/GSX's swing arms. 2 different hubs, what spacers go where and stuff like that

Lots of combinations...............

I spent a lot of time doing mine in powerpoint, and it was a struggle.

Easier to do it in the metal. Up on a hoist with the wheel aligned and centered, pair of good inside calipers - and a lathe....

 

[Guest]

Correct me if im wrong but the ‘78-‘79 gs1000 cush drive has 6 blades for the cushions to sit between and the gs500 only 5... how did you make the gs500 cush work with the rest of the gs1000 hub? Im away from home for 10 days so cant fondle the gs1000 parts to imagine machining them to work lol....

Yeah GS1000 is a six. GS500 is a five.

My bad. We used GSXR cast wheels.

Looks like a machined spacer for the rear sprocket is going to be needed. If it is, I'd do it stepped inside and out to get positive location.

back to using a spacer, should be easy enough using washers to get the length then have a aluminum ring machined. Maybe longer bolts as well.

Next question is .. does anyone have experience with selecting a 520 chain ring that fits the oem hub? Say oem amount of teeth and/or 2 up or down? I suppose talking to suppliers I can get some answers but thought id see if anyone here can give me a starting point or advice. Thanks

here's a 1 year only 18x4.5 wheel with a 160 on it....bought the bike like this.
i believe the front is a GS500 wheel...they match anyways..
