I also have the yam tail tidy and yes it is a pain to get the cover over the lock
Have you fitted the extra part or not I have not had any issues after fitting
You right lots of photos of it on the tracer but I was looking for it in the standard mt09 and what people thought of it
My mate has an tracer with full shad luggage but or see ant on a standard mt09
