Okay, I've got to ask this.
What vibration?
My 500 doesn't vibrate. Yeah, at tickover as it's a big single but, still - not much. Certainly not when I'm riding.
Yet I see lots of threads and responses about all this vibration.
Either
A] I don't think it's excessive
B] I got a magic, vibration free bike
C] People are too sensitive
It's not like I don't know both sides - my HD was atrocious at tickover, literally shaking my eyeballs at standstill - my GoldWing, which I rode for 3 miles with the dustcap sitting on the pillion seat.
