To summarize this correspondence that took place 1 year ago:
Finally, I have chosen the Yamaha Tenere 2009 (XT660Z).
After almost 1 year travelling with it I can confidently say that it was an excellent choice.
I wrote some points that reflects my personal experience with it.
It reacts and feels exactly as a Yamaha Tenere single cilinder should. Basically it has the same good & simple engine as previous models but with fuel injection that powers him more. Easy to ride and control on & off road.
Not too much electronics comparing to the alternatives - Although the bike has much more electronics than previous versions of the Tenere, it's not too full of it. I guess that those days it is almost impossible to avoid too much electronics in new bikes but in my opinion, the new Tenere has a good balance of it.
Easy to fix - as stupid as it was, I ran into a (too) deep river in North Mozambique and got stuck with a damaged Head Gasket
. I was fortunate to locate a former Zimbabwean guy who ownes a Marnie Mechanic Shop in Pemba with good Western tools. With the help of the manual and his previous knowledge of bikes he managed to replace it (after 3 weeks of waiting for the Head Gasket to arrive from Germany). If it's the bike or him, who knows... but the result was good so I decided to include that point.
Durable - we had 2 rough crushes and few more fallings. It only resulted in a few scratches and front wind shield crucked. In addition, 3 days after the river incident, I was trying to evacuate my self from the village I was stuck at to the closest city, Pemba. Due to previous failure, I took the locals advice and placed the bike, my self and all the gear on a Canoe with which they move scooters from bank to bank in a deeper part of the river. After about 1 minute in the water, the canoe flipped and every thing including the bike was in 2 meters' deep water. The bike spent about 10 minutes in
the water until we managed to push it out to the other bank. 9 months later - no electronic problems.
23 liters fiberglass fuel tank (!!) and a fuel consumption of 17-23 km/lt (depending on the style and terrain).
Good looking bike!
Chair is not extremely comfortable. It's not that bad but after about 4 or 5 hours of riding the butt starts to attract attention.
Awkward access for repairs - for example: in order to replace the Head Gasket, you need to take off almost all the bike - fuel tank, rear wheel and spring & the all engine! Stupid but thats the price for all the addings.
It's not a 900 or 990 or 1200 cc and of course a single engine suffers from less power in low RPMs.
It's not amphibian
Here are 2 pictures.
All the equipment (including change of exhaust) was purchased from and fitted by Off the Road, Cologne, Germany. I have only good things to say about the equipment's quality and the prices!
Well, I guess that is it.
Good luck whatever you choose.
