Welcome dude.
The KLR does not have such a long history in the country, the A model we now love so much has only been here for about 3 years.
But its show itself to be a great performer for all tasks African.
In the rest of Africa you dont need to ride at 140kph a lot, only covering long distances in South Africa/Namibia/Botswana does this requirement pop up.
For the rest of Africa t0he roads are the ideal terrain for the KLR.
Add the reliable torquey engine with cheap and easy to maintain components and you get an awesome Afrika Bike!
The performance offroad will not dissapoint you like an 1150 Adv and then cruising on the tar will not be as much of a pain as a 640 Adv.
There is a list of precautions I would take however.
Doohickey
Waterproofing (t-mod , new sealed bearings)
Tyres something knobbly, spare tubes. (Maxxis 6006 for R400, cant go wrong here)
Re-route dual control cables , clutch at least
Radiator guard , maybe bashplate and pump guard.
Spare levers, metal reinforced handguards.
IMS tank on the ultimate Africa tourer, but standard does well enough.
Some form of rack for bags. Helps when pulling or pushing the bike through rivers/mud too.
Louis one for sale on this Forum is pretty close to ideal. Just slap in a doohickey, do the waterproofing, tyres and you are good to go.
