Unlike a traditional sidecar added to a motorcycle, the GG Duetto is built to function only as a sidecar. While many manufacturers offer kits to convert existing motorcycles for sidecar operation, the GG Duetto was only sold as a fully assembled vehicle not registered as a vehicle produced by BMW motorcycles.
