I'd be worried about the battery dieing on the road somewhere. What if
instead of a steer by wire, you make a power assisted steering. Instead
of replacing the mechanical link totally, put an encoder on the
handlebars, one on the front wheel, and a servo on the front wheel. Then
use a PIC (of course) to measure the encoders. When you see the front
wheel encoder start to oscillate, generate counteracting forces using
the servo. If the rider is truly trying to turn, you'd be able to
measure a change in the handlebar encoder as well.

Just some thoughts.
