Faults:

No serious problems at all. A very dependable, low maintenance ride.

Valves on mine are a bit noisy, and a valve adjustment didn't seem to make much difference, but a half-can of Winn's Engine Tune-Up works great, quiets them right down.

General Comments:

I really enjoy this bike. It's not screaming fast, but very competent, and gives a nice rush of speed in the higher RPM range.

It corners very well with good tires, and it never gets scary.

Seat comfort is good to adequate. I'm quite ready for a stretch and to walk around about the same time I need to tank up again.
