Kz900 Ltd wheel swap on extended swing arm.

Some bike/wheel info and pictures would very helpful.
We all here don´t ask the crystal sphere for any helpful hints...

Depends  on what swingarm you are using. If it is wider than stock, then you likely can adapt most any modern sport bike wheel that is wide enough for the 180.

Also be sure to consider the clearance between the chain and frame if you use a wide rear wheel / tire.  I don't know the limit, but if you go too wide the chain will rub the stock frame.  Ed

 He will need a min. 10 mm front offset sprocket, anyway what kind of swing arm/wheel (5.50 ") he want to use with a 180 tire.

Sorry for some reason I thought I put that in there. It’s a 76 kz900, everything is factory minus the motor, it’s had some work done to it. I’m going with a D&G chassis 8in over swing arm. I found a good deal on some 2001 gsxr wheels, I haven’t bought yet just because I don’t know if they will work. I know I’m going to have to play with offsets and a little of  fabrication and I’m ok with that. 

I suggest you call and or e mail  Les Holt  who is a  member and vendor here on KZRider 

Look at the bottom of this page and contact him at PDM  fabrication.

He has helped many members here  with  advise and  parts if needed to do a job like you are  doing
