I fitted a rack (brilliant bit of kit made by johnakay) and a top box. Before the fitment the rear of the bike was always clean. Now when I go out in the rain the number plate, top box rear, tail light and rear plastics are covered in road spray and dirt. Looks like I'll have to make a mudflap. I'm not keen on spoiling the look of the bike but I ride all year round so it's a must. Any suggestions or help gratefully received.
