I too am working on the airport project and currently ride a Kwak KLR650.... if you go in or out of SQ entrance i've probably flown past you at one of the speed bumps. I've been here since September and am a very happy biker although the sand on the roads can catch me out on occasion (thank feck i'm not on my usual 1000cc sportsbikes!)
If you are interested in a beer so I can tell you all about it then give me a shout (I live at Dolphin village) and I can sum up my experiences of Muscat so far. Also, I am selling the KLR
as I won't to move to CRF or something similar (i.e. off-road with some on-road rather than on-road with some off-road).
Hope you're enjoying the place!
