Years ago I upgraded the stock spoked wire wheels to DID alloy rims and SS spokes/nipples, a 2.15" x 19" front and a 3.00" X 18" rear on the reinforced but stock swingarm. Handling improved as I changed the front fork damper rods to later model KZ900's along with Progressive front springs and Progressive rear shocks. So the stock geometry was not significantly changed from stock if at all by the changes. I braced the frame a long time ago by the way.
In 2006, I replaced the DID alloy wheels with wider 17" Excel alloy wheels wide enough (3.5" and 4.25") to support the use of radial tires, and added a GS1100 swingarm and a rear disc brake setup. Here I had to consider how this bike's geometry and total height/ground clearance would change along with its handling because of the 17" wheels. I even took into account the actual diameter and width of the Avon AV45 and AV46 tires I wanted to use, the resultant trail changes, wheelbase change (the GS1100 swingarm is longer than the OEM Z1 swingarm) etc. I missed one important item that surfaced with use of 17" wheels and OEM KZ1000 front and rear calipers: I will spare you the details for the moment.
im sure i can figure those out ,
i did find out this dose have front and rear disk, dual up front.
so that at least makes me feel some what better. how ever still would not mind finding something to do with the swing arm to make it a bit more stable and also help the performance on it. not looking for a drag bike, but like that look.
