I have no standard shift points, I go according to conditions and how I am feeling at the time. If I'm feeling leisurely, I'll short shift at around 2500-3000. If I'm in a sporting mood or want to exercise the bike a bit I'll take it well into the 5000 range and occasionally right up to red-line. Have never hit the rev limiter on the 1800. As I mentioned in aother post, these engines are meant to rev, so let the dogs out once in a while.
That's the beauty (one of them) of a Wing. You can cruise through a town and not even down shift (cause I'm too lazy to take my feet off the cruising pegs). It still amazes me how low these things will rev and maintain an acceptable speed with no "chug". Gotta love it.
