Does anyone recognise what Yamaha bike this seat is from? Its definitely a Yamaha seat (it has its original Yamaha cover on it) and I think its from the early 1970's. I bought it to replace the non-standard covered one currently fitted to my very original 1973 Yamaha TX750 four stroke twin. It is marked by the vendor as a NOS TX750 seat, but, it doesnt fit my original bike! Its longer than the seat pan fitted; has different indents in the seat pan, and, most importantly the hinge points are further apart than on my original '73 frame. Any help and ideas would be really gratefully received! Thanks.
