I saw this at a recent bike show
SIDE - Simpson Detour not pretty but much better then most after market headlights.
Most after market head light fairings attach to the front forks, on my XT600 3AJ the headlight fairing would hit the tank when you turn the handle bars.
You should also check the wattage of the bulbs is not higher then the oringal as this can be a problem with keeping the battery charged.
