No markings other than the one tag in the photo. You can see some slight differences in the case, so I suspect it is a knock off and not made my Mitsubishi. I think the Sears site lists it at 80 amps. The OEM Honda alternator capacity spec in the manual says it is a 1.2 kWatt alterator at 5Krpm. If you multiply 80 amps by 14 volts, you get 1,120 watts, so it looks very close in the "listed" capacity.
So just judging by the amp rating on it, it looks like it will work, and it does fit the bike and plugs in just like the OEM alternator. When I start the bike, it brings the voltage up to about 14.2 volts so it looks like it works ok. The real proof will be in seeing how long it lasts. Glen seems to put a lot of miles on his bike (currently over 250K) so I guess we'll know fairly soon how reliable it is.
