So, as I'm continue my R60/5 project, the rear shocks seem to be shot - they're at the highest tension setting and are pretty relaxed, for a lack of better words.

Looking at Hagon, Progressive or Bob's BMW has replica type shocks.

Before I pull the trigger on new shocks, wondering if stiffening up the suspension should help a bike like this handle better - right now, a "cushy" ride. I also plan to change fluids up front in forks.
My R65LS with new Progressives handles pretty awesomely - not sure the build of the R60/5 LWB lends itself to "better" cornering, etc.

Insight, wisdom??
