Good shock fluid as described
Good fluid. Used to replace shock fluid in 2005 Electra Glide. Did not notice much difference and ride but it is nice to know that the fluid is new.

and found the ride to be better than when the shocks were brand new
I used this in a pair of 12" aftermarket air-assist shocks intended for a Road King but mounted on a 560 pound Sportster, and found the ride to be better than when the shocks were brand new. This 7wt fluid provides just the right amount of damping in this set-up solo (ca. 180 lbs.) as well as two-up (ca. 300 lbs.), including with an additional 100 lbs. of baggage. I would highly recommend it and will certainly look for it again the next time I service these shocks.

Good Shock Fluid
Good viscosity and high viscosity index for many common motorcycle shocks. This is a proper shock oil and not fork oil.

Perfect as an upgrade to stiffen rebound
Used this as a replacement in a 2006 FZ6 forks to stiffen the mushy front end. Perfect low budget upgrade instead of new springs.
