Tach people, have to get the exhaust system for my TZR before me. It has no TÜV. Now a question. Is it not IRGENDWIE possible to have them registered. I have a Mofadrosselkit and so is se. the exhaust would not change the performance at all, because because of the Mofadrosselkit the exhaust was removed anyway, because otherwise it would have no power at all because of the electronic speed limit. Then it would have to be somehow possible se I mean……always a lot of people build themselves a bike (brand: self-build) and get a road registration for it. MFG Stocki
