I'm thinking of replacing the shocks on my '82 KZ550A but every maker sells them separately from the springs which need to be mounted. Ok, I can understand that, different springs, different rates. Other than going to a dealer and paying loads of money because then you'll have to buy it from them, and again, understandable, how am I supposed to get springs mounted on my shocks? Is it very difficult to make a spring compressor? I want to buy new, not used. Why doesn't Progressive mount some springs to shocks in popular rates? From my research the Progressive shocks for vintage bikes are only made for a few years applications, ok, so make up a bunch for those years, you'll sell every one of them. Am I missing something cause its been over 20 years since I've looked into shocks for this bike.
