Hello, I’m a female from Hamburg about half a century old and I’ve never driven a Harley before, let alone possessed. My bikes were mostly “Japanese” and my current is a Custom XVS 650. But this could change soon because I was allowed to take over from the widow of my deceased neighbor div. motorcycle parts, in return only the garage had to be cleared……I liked to make it. Now I own a lot of parts for the construction a Harley and have already informed me on the internet plentifully about the costs so everything will come to me and whether a construction is worth it. A cost factor is, among other things, the purchase of a control unit, I hope I give this right now and that it is about the TSSM with FOB and alarm. At the Harley dealer this costs already a lot, therefore my question: Can I buy a used one without FOB, this then separately and there is something important about it that I In the bay something used is offered more often. I am happy about information possibly also offers and if everything works there is next year a Harley driver more
