Most KZ standard models had a 19" Fr & 18" Rr. The Ltd & CSRs had a 16" Rr.
I think the KZ1000-P police models had 18" Fr & Rr.
I believe most of the 70s wheels are tube type (TT) & most of the 80s wheels are tubeless. Since your bike is an 81, I would get 80s wheels. 1980 was kind of a transition year, so some of those may be tube type, which I would avoid.
As for the stance, the CSR probably has leading axle forks, having the axle on the leading edge of the forks.
Standard models had center axle forks, so the axle is in line with the forks.
The rake angle varies as well.
1981 KZ650-CSR. Competition, Sports & Road.
