I have an MZ ETZ 250/300 for sale. Previous owner bought it new and had it converted to a 300 before taking it from the shop. It is a 1989 model. 1 caarefull owner before me, full servive history, with plenty of MOT certs. It is SORN, and was taken off the road a few years ago when it failed an MOT on a warped disc. The guy is a driving instructor so didn't need to ride it, put it in his garage and there it sat. I put fresh fuel in it and a battery from my gsxr and it fired up.
Here are a couple of videos of it running.
