Just to endorse what HA has already said about getting a bike licence here. I too thought on arrival that my combined (UK) car and bike licence would simply be converted to the Kuwait version, as is the case in the UAE, but no such luck. It's a straightforward swap for the car licence (no test, and I'm pretty sure it's ghe same for US licence holders too after attestation by the embassy), but to get my Kuwait bike licence I had to sit a test (!) which I failed the first time (!!) because I didn't understand the (Arabic) tester's instructions and crossed a line when doing a figure of eight - all very embarrassing at the time. Got through no probs next day however. All this costs money of course, endless paperwork and lots of stamping and signing by officialdom (they've taken bureaucracy to a whole new level). I'd recommend having a mandoub with you if poss for translations - unless you speak Arabic. Again, as HA says, Tristar can and will help if necessary – ask for Salem.
As for going off road, there’s not a lot in the way of dunes here. The desert’s flat, stony, scrubby and not really very interesting, plus a lot of it is fenced off to ‘protect’ oil installations/pipelines. Add to that the recommendation NOT to veer off identifiable tracks because of unexploded ordinance left behind by the Iraqis – they still find stuff every so often… But there is a dirt track and an ex-KTM Team rider called Mark now working for Tristar who is doing what he can to generate interest.
But bikes here are expensive, even second-hand - they blame the small market. However, I do happen to know that Tristar now have a very good ’06 640 Adventure with a ridiculously low mileage at the moment because I’ve just traded it with them for an ’06 1200GSA. Low mileage because it sat doing absolutely nothing from more than a year while I moved from Dubai (where I bought it) back to UK, then to Kuwait (long story) but it’s a great bike. I’ve switched to the BMW because I plan to ride back to UK when my time is up here and didn’t fancy doing all those kilometres on a single pot. Get in touch when you get here. Cheers, Dave
