I am 150lbs rider looking to upgrade the rear shocks on my 1971 CL100. I have tried two sets of progressive shocks from eBay (advertised for CL100) but they were both too stiff and I am done with eBay. Stock works great but sometimes things get out of hand in hard corners, and I'd like it to go around corners better and give a smoother ride. Can anyone recommend some options for an upgrade from stock?
