It's illegal because the product is sold to be used on only one bike/ecm, and the folks doing this are taking units that have been used previously and hacking the electronics, then selling them to someone else. Now that Harley is no longer allowed to be in the SERT business, I don't imagine they will seek out and sue these people out of existence, but that doesn't make what they do legal. To some people like me supporting thieves isn't an option, to others it's not a consideration. To each his own, I just thought I'd let everyone know these are illegally modified parts and not just a pile of unsold leftovers from Harley.
