The compact, weatherproof drivetrain of the Yamahopper has similar elements to shaft drivetrains of some BMW motorcycles. Its simple, maintenance-free shaft-drive contained in the single-sided swingarm eliminates chain maintenance, safety and wear concerns as well as weather wear factors and contributes to the durability and ease of use of these tiny motorbikes. The drive unit also incorporates a traditional centrifugal clutch but only a single speed gearing, unlike some mopeds which have two speeds. The simplified driveshaft setup makes wheel changes easy.
