I've measured the bushings and shock post carefully. Current bushings on the KONI shocks have an inner eye diameter of 16mm which is the largest diameter bushing KONI/IKON makes. There is no larger size.
The current Honda stock shock has an inner eye bushing diameter of 17.5mm and the shock post is the same at 17.5mm. The 16mm KONI is too small to fit. Even more perplexing is the current IKON shocks sold for the Honda CB750 must use the 16mm bushings yet that is too small for my bike?
The Koni shock appears to have a metal sleeve that is not needed, try punching that out and see what the dimension of the rubber bushing is.
Measure the OD of thr metal bushing 1st
