Timo Lahti has a Swedish passport on account of him riding in Sweden for numerous years, but it makes him as Swedish as it makes me a Finn (my wife being Finnish).
Rding on a Swedish licence is out of convenience too, as although he is a Finn, he counts as a Swede for team building purposes in the Elitserien.
Sadly speedway in Finland is really struggling, withno meetings held this season, due to the well documented insurance nightmare. Otto Raak being picked at reserve is largely due to their being no one else left to ride, rather than his ability as a 16 year old up and coming rider.
