HID can be a bit dodgy electric-wise on a bike, and there are legal issues to do with it requiring self-leveling. Don't think you can fit them to high beams either?
The self levelling is a PITA. But then again so are small plates and other stuff.
ALL headlights really need to be wired into relays. It's ruddy amazing how much more light you can get out of standard 55w halogens if they're fed by big fat wires.
The only issue I've found with HID is that they need good voltage to fire up -if your battery is dodgy or alternator a bit feeble they sometimes wont fire up. Once on they're way better than any Halogen. Also it has to be said that blue-ish tinted HID's are not friendly towards plastic reflectors/lenses.
There is another option for non-H4 users - LED bulbs. These are now appearing with decent wattages and lumens output. I've some H3 on order for testing in fog/driving lights.
