The Vetter Streamliner was a feet forwards motorcycle made by Craig Vetter in 1980–1981 to demonstrate high fuel economy with a streamliner fairing.

Design[edit]

Vetter had been creating his Vetter "Windjammer" fairings for some years before the Streamliner was designed, and created the Craig Vetter Fuel Economy Challenge to heighten interest in aerodynamic-conscious design. Vetter's objective was to surpass the economy of the 1980 mileage contest winner, a conventional Harley-Davidson with tall gearing.[1]

The Streamliner was built around a Kawasaki KZ250 custom touring bike,[1][2] with foot controls moved to the front. In contest conditions the machine achieved 108 miles per US gallon (46 km/l)[1] (125 mpg in best-case conditions[3]), versus the manufacturer's claimed 80 miles per US gallon (34 km/l) for the original, unfaired model.[4]

Vetter now considers more than 8–10 hp overpowered, and has said that selecting an engine with the appropriate power output is "critical" for mileage contests.[5][6]

Influence on industry and legacy[edit]

Vetter’s streamliner is credited with "inspiring others to push the limits of motorcycle fuel economy,"[1] with many other entrants in his mileage challenge and one electric motorcycle modeled after Vetter's original.[7]

The Vetter Streamliner is now on display at the AMA Motorcycle Hall of Fame Museum in Ohio.[1]

Other streamliners[edit]

Vetter also created a fairing for a downhill skateboard speed contest in 1978 which bore the name "Vetter Streamliner."[8] It was featured in a 1978 CBS Sports Spectacular broadcast from Derby Downs in Akron, Ohio.[9]
