I get some scrotal discomfort on my FZR1000 after about 100 miles.Even with the Corbin seat,the bars are pretty low on that bike,and I end up near the front of the seat.It doesnt help that it has a little "kicker" in the front of the saddle that usually ends up crammed in my crotch.Ill usually scoot back a little,then put a some more weight on my hands,to take pressure off the seat.Makes me with I had a gut to rest on the back of the tank!
I shouldnt complain though,when we all ride down to Laguna Seca for Superbike Weekend,my buddy who rides a Ducati 750SS is nearly screaming in pain by the time we get there.Hes good for about 50 miles initially,then about every 5 miles after that,I see legs and arms start sticking out in all directions.
No discomfort from the B4 when stock,although I only rode it for a limited time before changing everything to this much more aggressive stance.Ill let ya'll know how it tickles me with the clip-ons and USD swap,once I get her done.
