Hrmph. That site's information is from 1990's, not valid anymore. Like Robert told, no insurances sold at borders anymore so get documents before the trip. Also there is no such "loophole" for russian citizens or temporary permits for vehicles anymore - ETA driving license is ok enough. You just need you car/bike registration documents plus proof of traffic insurance which is valid in Russia too - so called insurance Green Card or similar.

Actually I have couple of times showed only international driving license in Russia - which alone is officially not enough - and no other questions asked, have a good day sir.
Most important point to have both international and original driver license there - if you have bad luck and meet official demanding to have some extra income immediately or pushing you to stay (go police station next day to solve the problem) - you can give them international license to keep and drive straight over the border with original one. In Russia, Police, Traffic Police and Border Guards are separate organisations. Which also means, if you happen to be stopped by local police for traffic penalty - overspeeding etc - they cannot give you fines but have to call traffic police patrol to do it. A foreign tourist, negotiation in such cases usually leads to solution - less work/waiting for patrol and just notice to you to be more careful next time.
