Hi Twinrider and welcome to Carpe.
I have been unable to discover the output capacity for you, despite checking everywhere I could think off. The only source I have not checked is a Haynes manual (I don't have one) but I am sure someome else will fill that gap.
But do not worry unduly, because unless you plan to turn your bike into a mobile Blackpool lights you should not have a problem.
