By the way I am in self imposed exile from MO for awhile till the GPTB Wild Weasels settle down.. This one-eyed pigeon is tired of being stalked and pecked to death....Think seruzawa has a good link posted on handle bars. But I've got a question? You got something against fairings? I think putting on helibars on a GSXR or RI is what I would do. I don't need to on my Ninja since it is 01 version. That year which had ergos like a VFR. I like fairings cause it easy to clean and keeps the muck off a ya..

I make my own headlight array from driving lights I get from Wal Mart.
I also found this when I googled "streetfighter motorcycle":
