Thought I share with the group. I purchased these rear shocks from Vintage CB750 for my '75 CB750K5. A repro set.
https://www.vintagecb750.com/products/3/suspension-wheelI know they are not the IKONs this group usually talks about, but for the price they have performed well over the last few rides on various terrain (dirt, concrete, loose gravel, bumpy forest roads). I have been riding around in the 3rd position; have not rode 2-up yet or with a heavy load. Will report back later. As expected, these are a world of a difference compared to the original rear shocks that were almost 50 years old on the bike. Lady damper has returned after her multi-decade slumber.
Anyway, my 2 cents. $125 for the set is ok by me.
