I think the mind has almost as much to do with getting a heavy bike on its center stand as does the body. My brother had a Norton Commando and he occaisionally let me borrow it. There were good days when I felt confident about kicking it over and, voila, no problem. Then there were days when I had this little teeny weeny doubt peeking out from a corner of my mind and DAMN! Felt like I been kicked by a mule.
So, this morning I decided to place my newly purchased Raven on the center stand. I weigh about 150 and had no real problem, although I was wary that the bike would lean to the right and topple over before I could stop it. I did make sure that I could feel both feet of the center stand parked evenly on the concrete... once I confirmed this I simply transferred all my weight to the center stand lever. Really, it felt about the same as putting my Honday Interceptor on its center stand. (Also, I had the side stand down when I did this. Once on the centerstand I put up the side stand.)
Now, having said all that, I confess to being a big weenie when it comes to moving the bike. That is, I always SIT ON THE BIKE and move it forward with my legs. Very inefficient, and stoopid looking too. I watch the sales people move their stock in and out of showrooms and it looks so damn easy. But I'm afraid. AFRAID, I tell you!
Tomorrow I'll put a Tiger Eye in my pants pocket and see if I can work up the guts to move my bike the right way.
