10 Amps at 9000rpm maybe, and even that is a big maybe. Max output means very little in most cases. The average output for most bikes that you really want to go off if is usually around 4000-5000rpm for any bike that doesn't generally go beyond 10k rpm.

In the case of the typical 8 coil stator, that is right around 5 Amps, give or take a little.
