Rear caliper dust seals from Wemoto are too wide

[His Dudeness]

In my experience after market seals are a bit hit and miss so I always get seals from Yamaha using the part numbers in the parts catalogue. The parts catalogue is in the download section http://foc-u.co.uk/index.php?action=downloads;cat=2  You know for sure the seals are the correct size and material when you get them from Yamaha.
