Indeed they are, but that wont be a workable defence when you go in front of the judge for unlicenced (if you don't have a motorbike licence) un registered and uninsured... around $2000 in fines AFAIK...
have you thought about compromising at a lesser wattage. if you get spotted much over 35kph you will probably get done.. I'll not harp on it, good luck..
If I see anything suitable on Ebay etc, I'll post it up for you..
