Royal Enfield Constellation
Royal Enfield's Constellation twin was the flagship performance model of the mid-1950s, using a 692 cc parallel-twin with twin carburettors and sports camshafts to produce the most power available from any British twin in production. Its polished ports and careful assembly made each engine slightly individual.
