Derestrictor boxes will always sell.
Ok, so many of you are now at the very least amateur mechanics. Partly through desire and partly through necessity. However, there's still a whole bunch of people who will forever struggle to remove a set of spark plugs (my big brother for example), and these are the guys that will buy a box. The thought of stripping a harness cover is enough to give some folk nightmares, let along snip a wire on a bike that should never have reached their shores and that you're average bike shop wouldn't go near.
As for the MC28:
As much as MC28's are universally disliked among many members of this forum, I'd just like to say that all you 28 owners should take your heads out of the oven as there is light at the end of the tunnel. You can relish in the fact that even though you may never beat an MC21 (or MC18 ) in a truly equal showdown, you will get a load more dosh in your pocket if you choose to sell it.
