It was advertised on Ebay as a 2003 Katana 750 rear shock and it appears to be in very good condition. It has a remote reservoir and I installed it on my GS but it was way too stiff so I swapped it out for a R6 unit. I would NOT recommend this shock unless you are over 200 pounds and it still may be stiff.
It's the one at the bottom of the picture.

So here's the deal - 1st PM gets it (lower 48 states only). Tell me your address and I'll ship it to you. I'll include a stamped envelope and you just send me back the shipping charge. It's just taking up room and I'll never use it so I figured someone else might want it.
PMed
Shock will soon be on its way to a new home.
