By popular demand, here is a brief guide on importing and registering a motorcycle.

1. Buy it in the States, get the title and a bill of sale notarized by a lawyer from the seller.
2. Drop it off in NJ for shipping; I sent mine to Kotka, Finland for $300.
3. Arrange for the shipping company to send the documents to Russia (if you are already leaving), otherwise, they will hand them to you or mail them within the US 3 days after the bike is shipped.
4. Wait for the documents in Russia, or if you arrived with them, go to customs. They will give you a short list of requirements, specifically that you need to translate the documents into Russian and have them notarized.
5. Pay the customs duties they calculate for you, take all the documents, and head to Kotka.
6. Pick up the motorcycle!!! Make sure you have the title. There are tons of taxi drivers there with vans who will take it to St. Petersburg; they hang out right at the customs office. I think I paid 15,000 rubles for that.
7. Head to the customs office with the motorcycle to get the PTS (vehicle title), then register it with the traffic police (GIBDD).
8. Enjoy!
