These shocks are amazing, just as good as Ohlins or Penske. I bought this shock for my K7 750 from someone on CL, had it rebuilt by Superplush Suspension here in SF and found out it's actually for an 01-03 GSXR 600/750. It's fresh as a newborn and ready to go. My loss is your gain. It is a BH6122 model and has a 8.0 kg/mm spring. I'm $500+ into it so far but I need the cash, so $450 shipped takes it. Yes, it has ride height adjust up to 330-340mm, and may fit some V stroms as well as the GSXR 1000, but I"m trying to verify that with Elka first, I'll update this post as necessary.
Bump this shock is still available. I also have a 9.1kg/mm (90 N) Ohlins spring that will fit it, brand new, $50. It's in my hands just refreshed ready to go.
