Not to start *another* shaft effect discussion, but the twist you
feel when revving sitting still is due to the larger fly-wheels that
the BMW R-bikes (maybe K's too, dunno) use. If you whack the throttle
at stop lights, it'll really rock the bike over (to the right).

Please post if you come to any conclusion on this. I am thinking
of putting a light on each cylinder guard on my R100S, and was
wondering whether I was going to have to switch lights off every
time I was under 5,000 RPM :-)
