The following was posted for me on a thread i started... i might help?
'You could consider doing the trip down in legs. First leg to Nairobi (asuming the unrest will have settled by October). Three or four months for London to Nairoby is pretty relaxed. There is a very good place to leave your bike in Nairobi, Jungle Junction. Maybe you heard of it, German bloke with motorbike work shop. Big enclosed area where lots of overlanders stay. He can take care of the bike, store it, run it regularly etc all for a very small fee. Friend of mine did it with his Landcruiser. Was there for a year and then he picked it up again to continue the trip.This way you would enjoy it as much you'd expect !'
Some day so soon....
