I am currently mounting a 1991 ZR 750 Zephyr swing arm on my 80 MkII. Using a 1992 ZX1100 rear wheel.

I am wondering about mounting a 7/8 offset sprocket, not sure if I need that much but this looks the closest, I will re-measure after I get the tire mounted to the wheel this weekend.

Will I need extra bracing for this offset? Like a bearing support?

Thank You

I belive someone makes one for a GS though, but I could be wrong.As far as I know...5/8 is the big one for a KZ, unless you go to 3" offset. 1980 LTD (changed over the years), 1979 LTD (being rebuilt), 1977 KZ turbo and various KZ's in various states of build.

I was wrong, and I'm glad.

I got the tire mounted this morning and got everything lined up nicely with spacers, and brake. And it looks like 3/8 is going to do it. I am glad I do not need a bearing support.

www.pmfronline.com/ do make a 7/8 offset for the KZ. I plan on buying from PMFR as they are local and I know John the owner. Hopefully I can get a discount.

Unless there is a cheaper alternative from another bike that works. If so please let me know.

Wasn't sure if 5/8 offset was going to be enough. Glad you started this! 1980 LTD (changed over the years), 1979 LTD (being rebuilt), 1977 KZ turbo and various KZ's in various states of build. KLX110
