1 EA AFTERMARKET REAR FENDER Z50A
 
THIS PART NUMBER IS ONLY CORRECT FOR THE "K1" MODEL, BUT I THINK IT WILL WORK IF YOU NEED IT FOR THE K0 AND POSSABLY THE K2 MODELS.

FROM WHAT I CAN REMEMBER THE K0 RR FENDER WAS PAINTED SILVER AND DIDN'T HAVE A TAIL LIGHT BRACKET HOLE.

AND THE K2 WAS A LOT LONGER AND MAY NOT HAVE THE TAIL LIGHT BRACKET IN THE SAME PLACE??
