Was talking to the salesman at local Harley dealer. He has a customer that had one shipped in and had them install it. It seems to be very street-able but runs very strong. Stated that bang for the buck was awesome.
Because it in against the law for them to offer it for street use as it is with many of their parts.
Other aftermarket company's get away with things HD would not.
Look what CA did to PC about a year ago.
