Number 1:
Watch your ears!

When driving with almost any helmet over 120 km's the noise from the
wind on the helmet is above safety limits! In fact, a study indicates
that:
...up to 105 dB(A);
exposure to this level for only 15 min would exceed the present
recommended maximum of 90 dB(A) for an 8 h working day...
And also that at 130 km/h the noise level is about 100 dba, and this is
not caused by the exhaust or other mechanical noises, but by the wind.
Most helmets do little if anything to protect against this noise.
Finally all motorcycle riders after a short ride at speeds such as 130
km/h experience temporary loss of hearing of some degree.

So the doctor's advice is USE EARPLUGS! in any trip outside of city
limmits, where you get higher speeds and where because of the wind's
noise on the helmet, you wouldn't be able to hear other important
things, such as a car's horn anyway.

Number 2:
What were they thinking?

We know that the Africa Twin was not designed with off road as a first
priority, but they did want to keep the image of the off road so they
kept the long suspension travel.
Only one little detail slipped their mind:
They didn't expect some crazy Greeks to really go off road!!
So what happened is that at the limit of it's travel the rear suspension
touched the exhaust!!!!! I now have a little hit on both my exhaust and
my rear suspension!

Go figure...
