Topic: cb500 or cb550 forks

[xsmooth69x]

i have a pair of 1971 cb500 forks and 1975 cb550 forks

my bike is  1975 cb550

is there any benefits from one or the other the insides look very different the cb500 has a metal rod running through the spring. what is that point of this?

The rod on the early forks holds the slider on and the later ones have better internal damping plus brackets for a second caliper
