I think it is 100 amp on an 03 and they changed it to 125 amp in 06. My memory could be wrong, I have seen it somewhere before but can't find it now.

My HELM Service manual for the 2006-2008 say it is rated at 1200 watts. That would be 100amps at 12 volts. Since it puts out 13.6 volts it is probably 88 amps.



If you run it at max output continuously you will shorten the life. I don't know how conservative the rating is though.

That must be what I thought I saw before, 1200 watts, not 125 amps. Still that's a lot of amps for a motorcycle, hard to overload it. The earlier models were probably 1000 watt, not 100 amp.
