Hi all, just bought two 1977 & 1978 CB750F2 supersports & have been renovating them. The 78' came in bits, the frame etc already painted & ready to build. The 78' is a complete non running shed of a bike. Just finished reassembling the 77' forks & realised they are approximately 30mm longer than the 78' forks. Upon a strip down the 77' fork stanchion pipes are longer than the 78's !! Does anyone know why as they are meant to be the same bike ?
