1961 MOTO RUMI 250 'FOUR IN LINE' (SPECIAL FABBRI)

The Rumi 250 Inline Four was constructed in 1960 by Giuseppe Fabbri, a former Gilera agent in Lugo di Ravenna, Italy.

The engine was created using two 125cc Moto Rumi two-stroke parallel twins. Only three of these machines were built.

Something of a legend, Fabbri created ten engines: two horizontal triples; three horizontal inline fours, two V-fours, one inline six and a V8.
