Ä° was in Ä°stanbul a few weeks ago and met a very helpful guy who ran a bike and scooter shop on the european side. We got chatting cos his dad had done a RTW a few years ago on a bike, he spoke some english.
He gave me his card ad said if i needed anything in Turkey or Ä°ran!! to give him a call and he would try to help.
His details are Mr Genc DEMÄ°REL at GENCSEBAT OTOMOTÄ°V, Tel; (0212) 2742727.
Maybe be worth mentioning, or not!, you got his number from the KTM Adventure riding BrÄ±t!!
Anyway, hope it helps, good luck
Some day so soon....
