Many people have not heard the Goldwing referred to as a 'Dynasty', but I find it to be the best way to describe a long running motorcycle name.
Within the dynasty are the families: GL1000 and the unicorn GL1000 12/74 and they are out there. The very rare 1976 GL1000 for the British the Goldwing executive with the Rickman fairing.
GL1100: Standard, Interstate and Aspencade
GL1200: Standard, Interstate, Aspencade and CFI
GL1500: 1500/6, Interstate, Aspencade, SE and Valkyrie
GL1800: with 3 generations. 2001-2010 gen 1, 2012-2017 gen 2 and 2018+ gen 3, F6B and 2 different Valkyries.
