How To Explain All These Engine Sizes Easily?

Are you shopping for a Harley Davidson motorcycle engine? You may have noticed ads for the engine sizes in CCs (cubic centimeters) while others use CI (cubic inches). It may easily confuse you, right?

CC stands for cubic centimeters. It is a measure of the engine’s volume. The higher the CC number, the larger the engine is.CI, or cubic inch, measures the engine’s displacement. The machine can move this volume of air in a single stroke.

Like CCs, a more significant CI number indicates a larger engine. In short, if you are concerned about power, then CI is a better measure. Again, if you are more interested in fuel efficiency, CCs may be a better indicator.
