I guess I had been so used to the "great" ride that I have been accustomed to. But recently I did two things that made a huge difference. I installed new IKON shocks on the rear, and new tires on both front and back wheels.
I took the bike out last evening for the first time on any extended trip - about 50 miles. WOW - this was the smoothest, most enjoyable ride I have ever had.
I can't think of ever doing anything so simple would make such a huge difference.
