Hello, I bought a Harley Fat Boy 2003 from Latvia. In addition, there is only one EU approval – paper (in my case (LT paper) green with some information. I have a purchase contract. Otherwise nothing. I also read a lot different here in the forum and have now got my own opinion. First I was with a screwdriver that makes Costom – conversions. He told me that he has done this before and said I need a COC paper. Hmm… that I have to see where I have the ( In short: The COC paper is only available from the Harley Dealer, for example, near you. The prices are moving… as you read here in the forum very differently. Between 150 and well over 1500 Eur there is the talk. After my screwdriver didn’t get in the pushes…. I released him from all duties and took care of an approval here in DE from now on. First I called the TÜV. He told me I needed a data sheet where everything was written on it. ch … the COC paper ? Hm that’s it… Ok I thought … I called Harley in Möhrfelden… the nice ladies on the phone told me that the COC is only sold through the dealers … She unfortunately can’t help me anymore.. but it costs around the 350 EUR. Ok I thought I was browsing the www Bin then with the help of another forum member on the TÜV Süd (data sheet until 1999) from 1999 to 2004 the Tüv Nord is responsible (later models are obviously not yet available) The price of the Tüv Süd per data sheet should then cost around the 300 – 400 EUR. I have a 2003er there is the TÜV Nord specialized. The costs here 350 EUR zuzügl 66,50 EUR MWST ( 416,00 zuzügl COD). If I now hold the data sheet in my hand and then go with my Harley to the TÜV… the acceptance and approval (provided that I hold the data sheet in my hand and then go with my Harley to the TÜV… should the acceptance and the approval (provided that I hold the data sheet in my hand… you have the original exhaust – which is installed for the respective type, a Km tacho and a couple of other modifications then hopefully no longer a problem. The Tüv acceptance according to § 21 is then perhaps also again at 150 to 250 EUR. That then depends on… what still has to be registered. I write next week or beginning of March… as it happened to me then at TÜV and whether everything worked out. Lg Markus
