Hi. Bit of a lat reply but maybe can answer a couple of your queries. I bought a bike in Kenya which I ride to Uganda and back.

The bike (Bajaj 150 Boxer) cost 1000 Euros brand new. Huge range due to 120mpg consumption, easy to fix, been a good buy.

Log Book: without a Kenyan PIN the Log Book could not be updated to include my name even though I spent a couple of hours on two occasions down at Kenya Revenue Authority offices. Use a PIN of a friend or family member if you can. If showing documents at border or in Police check I always can show them the receipt for the machine and they accept my explanation about the PIN. Insurance was easy to arrange. I added COMESA insurance document too.

Kenya - Uganda border : This can take between 30 and 90 minutes to clear. 4-stage process; 1. Exit Kenya. 2. Sign papers to export vehicle from Kenya. 3. enter Uganda. 4 Import papers must be obtained from Customs. ( Much friendlier this side than in Kenya).

Crossing at Malaba is more modern and more organised than Busia.

Uganda will grant 2 weeks free riding after that you need to go and pay road tax, this cost me 69.000 Ugandan shillings (£14) recently. Keep all documents handy as these are inspected closely at the border, sorry if that seems obvious but they do go through with a fine-toothed comb.

Look forward to learn of your experiences.
