Progressive Suspension rear shock for ST1100

Good shock. You won't be disappointed. Be sure the spring is suitable for your weight.
I had a 420 Progressive on my ST1100 for many years. The 420 is an older Progressive model, the 465 is a newer shock and somewhat better designed but overall I would not hesitate to buy a 420.

IIRC, they don't rebuild the older shocks any more - but I could be wrong.
Wilburs also makes a nice unit.

There may be someone else that can rebuild them when the time comes.
Progresive made a good unit but when they started refusing to rebuild the older ones, some folks walked away from them.
I know the post is an old one, but I just saw it.
Here is my experience with the 420 shock from Progressive
I bought it and mounted it long time ago. As I remember, I never liked it a lot. It was hard then. Bike sat in storage since 2009, after maybe a 1000 miles of use of the shock, if that. So not much of use.
When I pulled the bike out of storage, I noticed that the oil seeped out of the shock, from the top, where the gas valve is. A. Echanic disassembled the shock and found the valve separated from the interior rubber bladder. It deteriorated. Apparently there is no way to reattach it, there are none to purchase, or nothing similar that we could find. Progressive was not helpful at all. They simply replied, this is an old unit, they don’t service the ST anymore, and good luck. I was disappointed, as I hoped to buy a replacement part, as I imagine , such bladder may be used in other shocks , or something similar.
Now the shock doesn’t work, and there is no rebound adjustment. I will look for a replacement for the next spring. And it won’t be progressive.

Yeppers, that's what I said in the previous post and your experience confirmed it.
I went with Wilburs on my ST1100s and I have been very happy with them.
Some folks go with Hagon on ST1100s and are happy with them.
Sadly, 'we no longer make parts for old stuff' is beginning to be a constant refrain from motorcycles to weedeaters ...
