I'm using the longer travel Ohlins 773 13" shocks. They do not use up valuable internal space for stroke length with adjustable valves or gas separating pistons. In this application more stroke is needed. Five inches of suspension would be good for a street motorcycle in general, but a stock Street glide has only two inches.
The Ohlins shocks have been professionally tuned on a shock dynamometer for our application and work great. Various spring rates are available based on the load you carry.
So why did you choose the Ohlins 773's instead of the HD-022's? I think the 773's are a couple hundred more expensive, right? Does the divided piston make that much of a difference?
