Could you say more about where you were, what sort of road, within town or not, etc.? Did these police speak English? Is it possible you were within a village or city of some sort, and they were telling you the speed limit once you passed a wee little sign with the town's name on it? This happened to me in Ukraine, and although the police definitely told me (in very fractured English) that the speed limit was always 60 for motorcycles, what they really meant was within towns and cities. It took quite a while to figure this out, though.

I road through parts of Turkey a few weeks ago, passing multiple speedtraps on all sorts of roadways without incident, and I sure wasn't keeping to any 77kph. However, it's hard to keep tabs on all those little signs indicating you're entering a village, and I had some narrow misses on that score.

As far as paying the ticket: did they run a check by radio or mobile phone on your ID or tab number? If not, they probably won't next time (!) either, which suggests not paying. To me, at least. Most places, when they really want you to pay they make sure you do it then and there—either directly, or in the next town while they hold your paperwork.

Big country, Turkey, even at 100+. My condolences and best wishes for speedy, worry-free riding!
