Quite many riders from Finland have been riding in Estonia too. But usually it’s only riding through as fast as you can! Riders from Finland are coming to Tallinn by ferry and then they ride straight to south!
But what if you’d stay for awhile?
It is true that there are not too many roads with nice corners in Estonia! But it doesn’t mean that riding here would be totally boring. The best curvy roads are in the coastline east from Tallinn (https://goo.gl/maps/n7Ej8PAaqb92) but you will find some nice roads also in Otepää area and in the Hiiumaa and Saaremaa islands. Sadly it is also true that if you find a nice curvy road it is quite possible that the pavement is not in very good condition.
But what is it then that makes the riding not boring? There are few good answers to this:
1. Estonia was a part of Soviet Union before 1991. There are many very interesting places to see: some abandoned nuclear missile bases, military fortresses, harbours, military airports or a submarine base.
2. Tallinn and Tartto are old Hansatowns. That means there are so many historical spots to see. There is also an old castle in Pöltsamaa, Haapsalu, Kuressaare and many, many other places too! (https://en.wikipedia.org/wiki/List_of_castles_in_Estonia)
3. Prices are very cheap! Last summer (2015) me and my friend stopped to eat something in Rakvere. We parked the bikes in the centrum and we saw a restaurant. The price for a russian kind of meal (some potato sallad, vegetables and a meat-saslik) was about 8 euros!
4. The nature is surprising! There are some cliffs, waterfalls, beautiful lakes, forests, very nice sandbeaches and so much more surprisingly beautiful places.
5. Huge motorcycle meeting in July in Jögeva! Usually something like 2-3000 motorcycle riders meet every year.
