It's always possible to fix something, providing the spares exist....is this the case with the X-wedge and for how long? I would have thought (hope) MMC would have bought up a stockpile
If something has been made, then it's possible to make it again. However, at what cost....
Were I ever in the position to own a M3W, I would probably look at the possibility of swapping out the X Wedge in favour of something from the Harley range - far greater availability for spares (and probably more reasonably priced).
