A motorcycle engine sold as a complete functioning unit is referred to as a crate engine. A crate engine is often used as a replacement when the original motor is in poor condition or to install a more powerful engine in the motorcycle.Continue Reading
The use of crate engines is popular with classic bike enthusiasts and racers as an alternative to time-consuming rebuilds or expensive modifications of existing engines. The name comes from the fact that a replacement engine is delivered in a crate with nothing else required for operation.

Harley Davidson sells new crate engines for many of their popular models, and S&S Cycle makes replacement motors for Harley Davidson frames as well as a range of performance crate engines for custom applications.
Not all bike motors are available as crate engines.
