SOLD - Please read the rest of the story before getting too excited. I got this shock, used, very used, from a salvage yard off eBay some time ago. Mileage unknown. When I checked the pressure in it, the pressure was low. I took the shock to a local tire store that puts nitrogen in the tires it mounts & balances, but found that it would not hold pressure. I called Progressive and was told it would still function as a shock, but without nitrogen it would loose its damping adjustability function. I was told $200 or more for them to rebuild it, depending on what it needed. While I was making up my mind I found a ZZR1200 rear shock at a good price on eBay, so I bought and installed that. I was going to take this shock to the trash, but I thought I'd offer it here before doing that. If anyone wants to try rebuilding it himself, or try using it w/o rebuilding it, make me an offer. If I don't get a response in a couple of weeks, I can still take it to the trash. SOLD
