Vibration is bad if it reaches the camera.
Wrap it loosely in a foam pad or similar and that will damp the vibrations.
Also, do not crash into large heavy objects - that will affect camera.
If its an SLR I would be most concerned about the mirror mechanism. Having said that, is one long motorcycle trip really any worse than lots of car/plane miles?
Also, I think this thread is a thinly veiled attempt to brag about your cool hog. It worked, so good job.
