You really don't want to ship a motorcycle into Egypt, and although travellers have crossed into Sudan from Ethiopia, we know of no travellers who have shipped into Sudan, so it may or may not be possible.
Try searching the Bulletin Board and the site (see Search box at top right of page) on the words 'shipping' and 'Sudan' or 'Egypt', ther are lots of posts.
Where are you going after Sudan? It would be easier to ship into Uganda or Kenya from UK, but I would recommend flying the bike rather than sea shipment.
Good luck and please let us know how you make out.
