No, no pain. Discomfort and serious physical and mental degradation (Especially Easy with this one Boys!

) but nothing hurt significantly.
When I first got the bike, I could not ride 4 hours continuously without physical pain. So I chaced down the root cause in each case; the first one was my butt of course. Several saddles alone and combined with cushions later, the combo that works for me is a stock Corbin with an Airhawk on top of it. Then my knees / ankles hurt; Buell pegs put my feet in a position to relieve that problem. 2" bar risers, combined with BMW sport grips (they are tapered and so effectively change the angle of the hand on the grip), coupled with a cruise control, eliminated all upper body / arm / hand pain. Finally, due to the more upright seating position, I added a MRA visor on top of a CalSci +6 windshield to put my head in a relatively quiet zone which along with earplugs, allows me to ride open- ended without hearing discomfort.
In my experience, if I can ride a bike for 10 hours or a bit more without any stops other than for fuel, I can ride that bike to the limit of my endurance, which according to limited medical records, seems to be around 60 hours <chuckle, sort of>. At the end, lots of discomfort but no specific pain in any particular area.

So how did you manage a CC50? Must have involved so serious pain.
