what is a good distance speed without causing damage ( cruising )[/QUOTE]
Hey, just a mention regarding running in, if your bike is still new. Like the rest have said, vary the revs etc, but something I was told was, if you run the thing in too slow, your bike will always be a slow bike. Dont be too scared to get the revs up there, without going too crazy. If you find that speed limit is an issue, run it at higher rpm's in 4th gear. I ran mine in at about 120-130km and now it goes straight to that as its crusing speed. These are tuff motors.
