Held for the first time in Europe, at the Big Bike Europe Expo in Essen, Germany, the event showcased the best in designs for motorcycles, scooters, trikes and sidecar outfits, with the 2013 AMD World Championship title won by Ireland's Medaza Cycles' creation 'Rondine'.
Don Cronin and Michael O'Shea, the two Irishmen responsible for the build, created a one-off frame to carry the single-cylinder, 1971 Moto Guzzi Nuovo Falcone 500 engine.
They were also responsible for hand-forming the aluminium bodywork and the heavily modified V-Rod swingarm, which is used as a girder-style front fork.
The Irish duo qualified for the competition by taking top honours at the international open qualifiers at the 2013 Carole Nash Irish Motorcycle and Scooter Show in Dublin in March.
Ruth Lemass, Organiser, Carole Nash Irish Motorcycle and Scooter Show, said: "The significance of this World Championship win for Irish custom bike building cannot be underestimated.
"Thousands of entrants from around the world went through a series of qualifiers and were eventually whittled down to 122 machines representing 23 countries.
"The fact that an Irish bike has won is fantastic and shows how far advanced our custom bike builders are on an international stage."
