Average dual seat to suit K100 8v series from 01/1986 on. This one is worn on the front and is splitting on the side shown in the last photo. The sponge is soft not hard like a couple I have had in. A good wool seat cover would tidy it up and would make it more comfortable to sit on. The base is in good condition. Please note that this one will not suit the early pre.1986 models as the pillion grips are not in the seat.
