Been routing through different sources for visas and the like and thought it might be useful to post some here.
Morroco
Good source of information on this very
site provided by Tim Cullis including information about
online documentation for a vehicles temporary import to the country.
Chris Scott's Sahara Overland site has a regularly updated
page worth reading.
While a passport will be required visas are not for members of EU countries for stays of up to 3 months. Visitors should ensure that their passports are stamped when they enter the country.
Passport valid for intended period of stay required
Mauritania
Passport and visa required for us all.
The French Embassy in London are representing Mauritania since they closed their Embassy in 2007.
Details of visa application are available
here Worth checking out as it would appear they need a lot of documentation.
Once again it's worth checking out Chris Scott's summary of
Mauritania.
Senegal
Citizens of countries member of the European Union (EU) do not need visa
to travel to Senegal for up to three months stay.
Must have the bikes logbook or equivalent with you not a copy and confirm no vehicle is being left in the country when you leave.
The Gambia
While a passport will be required visas are not for those traveling on British or Irish passports. Not clear from what I could find on the web the situation for the Irish so I rang the Embassy to check.
Also asked about temporary importation documentation for a vehicle and was told " I don't think we need a form" so will email for confirmation.
