This is the very first “luikkutankki” (flap tank) SM model produced by the Bensow factory, known for making Solifer mopeds. This particular unit appears in the model’s promotional photos, the service manual, and was officially type-approved in 1977. The moped was found in poor condition in Nakkila in 2022 and has been meticulously restored to its original glory. This moped represents a significant piece of Finnish moped history.
