Took the JP out today.Did about 10 miles by myself on some roads I usually avoid. Great improvement. The wife and I did about 100 miles. Great improvement. After riding awhile I said "What do you think?" She said "a little better". Then I hit a couple good bumps, that typically would knock the wind out of me, and relocate a kidney. Asked her again, she said" Yea, its definately better. There should be some KP shocks around from the guys who upgraded to the penske. For me it was definately worthwhile.
I'm about 215, the wifes about 150, if this helps at all.
