Street legal Supermoto conversion

I am planning on picking up a 2006 YZ450F and converting it to a street legal supermoto. I won't be going on long rides like a harley or anything, but short trips and possibly racing it in the future if I get hooked. (I was turned on to it after checking out the DRZ400SM at the dealer, but wanted to personalize it more, have it lighter, plastic tank vs metal).
I have done some scouring on the net and have found some places but wanted to know if anyone else could direct me to some other links or what.
I see that Baja designs makes a quick release light kit for about $500, plus I would have to buy a stator for about $500 as well. I was planning on keeping my 250f for rocks/beater bike and having the option of swapping the wheels off, lquick release light kit and being able to ride the 450f here and there on the track.
I was thinking besides the light kit and possible 2nd rear fender to house taillight, blinker, plate holder, to also purchase 2 17' wheels and tires, oversized front brake rotor and have the rear wheel with a lower tooth sprocket for the road. I would probably send out the suspension, I am 180-185, is this necessary? oh yeah, other trick components would be the handguards, shorty front fender, steering stabilizer I guess....
If anyone has any input or has done this, whether good or bad, please let me know.
Thanks, Chris.

I have met several people here in Maryland that have converted YZ/WR 400/426F's to street legal dual purpose bikes. Bikes sold here in Maryland also are registered/titled. I even have insurance on my 250F.
Yeah, I figured a little over $1k for wheels, $1k for the light kit and stator...Probably gonna cost about $10k all said and done.

Does anyone know of a web forums site that is for supermoto?

somewhat answered my own question. I did a google search and came up with supermotojunkie.com
In case anyone else was looking for such, FYI.

Yeah, I have checked out the DRZ400SM, both black and yellow, at the dealership - $5999 or so.. But weighing at 293, I would rather go a little bit lighter.
I primarily ride dirt, just wanted to be able to swap back and forth if I wanted. So I probably wont go totally nuts on it like lowering the suspension an inch or such.
I would do it to my 250f, but I think it will rev out fast and think the 450 would be much better. plus I would have both bikes as options to ride in the dirt.
Oh well, my fault that got me into this mess. :bang:
thanks for the input though.
