Understanding Motorcycle Engine Sizes and Power Dynamics

When considering a motorcycle’s performance, many riders focus on engine size, often expressed in cubic centimeters (cc). Engine displacement is certainly an important factor, but it alone does not directly determine how much power a motorcycle produces. 

In this article, I will explore the nuances of engine displacement, power output, and engine architecture. By the end, you’ll understand why choosing the right bike for yourself isn't as simple as just looking at the engine size.

What Is Engine Displacement?

Suck, squeeze, bang, and blow—this is the wonderful method that stirs our souls aboard our motorcycles. It’s an elegant (if somewhat naughty) way to explain how a four-stroke engine produces its power. 

In reality, though, there’s more to it than just those four magical words. A critical component is exactly how much you suck, squeeze, bang, and blow. This is described by engine displacement. 

Specifically, engine displacement refers to the total volume of all the cylinders in an engine, typically measured in cubic centimeters (cc) or cubic inches, if you insist on using Freedom Units. It is a measure of the space in which the fuel-air mixture is compressed before ignition.
