A donor bike is a ridiculously small mini-motorcycle that has become a nationwide menace the past few years. Donor bikes are identified by the presence of an idiot behind the handle bars, no helmet and a blatant disregard for traffic rules. Additionally, 80% of riders at some point become organ donors after the required fatal crash.

A motorcycle that was once on top for performance, but like everything in history, it now loses due to new designs from the other manufacturers. In 2005 the new "Gixxer" was king, in 2008 it is now dead last. Motorcycles are updated every 2 years with complete redesigns every 4 years. The cycle will continue and with all the manufacturers fighting to be number 1.

The GSX-R is not the be all end all of sport bikes and is usually piloted by someone new to bikes who has no clue how to handle the power, and only bought it cause its a GIXXER! Usually accompanied by someone riding in a wife beater, shorts, flip flops, and optional helmet.
