My '91 katana 1100, even with a perfect always had a bit of a buzz. As I got older,
I developed arthritis in my hands and despite gel grips with gel wraps, with finger less gloves w/ gel inserts with gel gloves over them, on long trips my hands would hurt. Hell, I'd double down on celebrex and pop a few codeine after a days ride and they'd still hurt!
Enter the '11 C14. First drive on it ever was 22 hours in two days. My hands didn't hurt one bit. Bike is as smooth as an electric motor.Smooth as Bill Clinton at a singles bar!
My point here is that your bike should also be that smooth.
