Hi Guys, I am after some info regarding a 1985 Honda CR250. The rear shock fitted to this bike is not 1985 and I am trying to identify it. There is HO441 stamped on the top mount block. It also has a black wheel at the bottom for adjusting the preload/rebound. What is the length between the fixing mounts that the correct shock should be. Any help you can offer will be very much appreciated.
