I have an NOS white M.Robert rear fender with the integral neumber plates. This is similar to the fenders used on 1981 KTMs, but I am not sure if this is an exact fit. I believe it is a universal fit model. The fender is new and still in the bag. $65 plus postage takes it. Get it before it goes to the 'bay. I would take an NOS 1980 KTM rear fender in trade.
