I agree, those will look very weird on a motorcycle. I can also guarantee that those will be blinding to any oncoming traffic. One of the drawbacks of LED lighting technology is that it almost always produces a lot of glare because there really aren't any reflectors behind the lamps to direct the light to the ground and out in front of you where you need it. These just flood light in every direction...not ideal for headlights but great for off-road use.

Have you looked at xenon HID headlights? Those LED light bars you are looking at are about 3000 lumens. Motorcycle HID headlamps will get pretty darn close to 3000 lumens and much more if you use two...and will actually look like the belong on your bike IMO.
