Highlights

• This exceedingly rare 1919 Harley Davidson W Sport Twin is the product of an extraordinary restoration, and it is truly a stunning machine
• The World War II-era XA is the best known of the flat twins, but Harley-Davidson also made this little flat twin in 1919
• With its dead-smooth motor, low center of gravity, light weight and good power it was targeted towards commuter and women riders
• The Sport Twin was Harley Davidson's first unit-construction machine with the gearbox housed within a common engine casting with the crankshaft
• The flat twin motor's Schebler carburetor used a "dust baffle" (air filter) for the first time
• More innovation included a fully enclosed chain, a trailing-link front fork and an external flywheel for the first and only time on a Harley Davidson
