The compression ratio of an internal-combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber; from its largest capacity to its smallest capacity. It is a fundamental specification for many common combustion engines.

Many high performance superbikes and sportbikes have higher compression ratios that require for the motorcyclist to use higher octane gasoline such as 91 or higher.
