18" wheel for shaft drive?

[Vishnu]

I have been wondering if there is a larger wheel than the usual 17" wheel that Suzuki makes for is shaft driven bikes. So far all I have found is the M109! At 8.5" wide, and a new swingarm its not the kind of swap I was thinking of. Is there another bike that uses a 18" rear with the shaft drive?

Mind you if I ever do a turbo hopup, maybe a wide tire like that would be cool ;-p

Why do you want an 18" wheel? All the GS shaft drive bikes (other than maybe the 450) use either a 16" or 17" rear wheel.

I want to reduce the rpm when at highway speeds. I have an 17" rim on mine, and I was thinking that a larger rim/tire combo would help to reduce the rpm to a slightly more economical rpm, as well at the same time increase top end speed (really thats a secondary consideration).

The '83+ 1100's use a taller gear ratio in the rear end which will drop your rpm's a little. I put one of those into my 850 - easy swap.

Ed,

I had considered a final drive swap, not sure if it would drop the rpm as much as 18" wheel with 130 or 140 tire on it.

cheers!

It would.

This message is too short...

[Vishnu]

Sorry I'll try harder next time.

too short how?

The forum software gives you an error message unless the response is at least 10 characters. My response "It would" was too short and generated an error.

mr. nessism,

My 850 sounds good at 5000 rpm but I would like a reduction as well.
I picked up a tired GS1000G for better high speed cruising.
More cc's = more fun. I am hoping to have it ready for spring. Too cold in my garage to put in many hours.

How much reduction in rpm did you realize?

check out this pic, it should help you figure out where youre at...

Thanks for the final drive spreadsheet.

I'll pull out the calculator to figure the difference on my 850 with a 17" rear tire.

I think Nessism got about 3-400rpm drop at freeway speeds.

Thanks Mr. Monk,

3 or 4 hundred rpm reduction takes the edge off the engine noise on a long ride.
