My Drz 400 puts out the same output, 200W.
I run heated jacket and gloves with a few modifications, the jacket is 70 watts and the gloves another 15. I made the switch to a HID headlight and LED turn and stop signals. I also added a voltmeter to keep tabs on the charging system. I never see the charging voltage drop below 12.5, never.
To be on the safe side I still turn everything off when I'm a few miles from my destination.
