Hello - I´m a new owner of a 2d hand ´90 750 Sport. Although it is a 2 valve 750 the bike seems very unique here in Germany Monsters and 998s all around. When I took it in to get it serviced after I bought it the mechanic was pretty impressed with the shape it was in for being so old. There were no changes except the original seat the owner replaced with a Corbin. Would be interested in other´s opinions on this bike and a possible source I could locate one of the original seats with cover.
