The Buell Blast is a motorcycle that was made by the Buell Motorcycle Company from 2000 to 2009. The Blast was conceived as an entry-level motorcycle to attract newcomers to motorcycling in general and to Harley-Davidson in particular. As such, the design goals were low cost and ease of operation and maintenance. Steps to achieve these goals include the use of an automatically tensioned belt final drive, self-adjusting hydraulic valve lifters, and a carburetor with an automatic choke. The engine design was borrowed from Harley's Evolution Sportster engine with the rear cylinder eliminated. The plastic bodywork pieces of the Blast were made from Surlyn, a substance used to make the outside of golf balls, to protect the surfaces when the Blast is dropped, and the color is molded-in.
