Be careful with the rpm/speed ratio. It varies with the diameter-ratio
of your front and back wheel, will say with the condition and type of
your tires, and with the condition of your chain. Additionally you have
to pay attention to the calibration and error of the speedometer and the
rpm-meter. So I can report rpms ranging from 4200 to 4800 at 100km/h
with the 16/45 transmission. The "design"-rpm-ratio by Honda is said to
be 22km/h/1000rpm with the 16/45. This means 4545rpm at 100km/h. With
this value you can calculate the rpm/speed-ratio for any arbitrary
transmission, eg. 4343 at 100 for 16/43.

According to my dealer the TUeV doesn't allow another transmission (it
was two years ago when I asked, maybe things have changed meanwhile.)
