Origins

This motorcycle was purchased from Thunder Cycle Designs in Fort Lauderdale, Florida, home of legendary bike-builder Eddie Trotta. Originally built as a service bike, this motorcycle would help to service motorcycles that had broken down. The bike was also owned by Arlen Ness who used it as a sign to advertise his shop.

The Duo-Glide is powered by a 1200cc overhead valve engine, nicknamed the “panhead” due to the pan shaped valve covers it uses. This was only the second overhead valve big twin to come out of Milwaukee, the first being the infamous “knucklehead” which now brings top dollar at auction and private sales. The twin cylinder engine uses Harley’s standard 45 degree “V” cylinder arrangement which produces that “potato, potato” exhaust note that Harley is known for. The gas is fed to the motor through a single Linkert butterfly style carburetor and the exhaust exits the motor through dual fishtail mufflers.
