The Honda Foreman ES uses a 475cc engine.
In practice, that displacement has been the standard for the ES variant across model years, with the ES designation referring to the electronic shift transmission rather than a different engine size. The 475cc four-stroke engine powers a single-cylinder configuration paired with Honda's shift-on-demand system, offering automatic or semi-automatic operation depending on the year and market.
Engine displacement in the Foreman ES lineup
Below is a quick look at how the engine size is specified for the Foreman ES across common generations. Note that the displacement remains at 475cc; changes over time have mostly involved fuel delivery, ECU tuning, and transmission electronics.
- Engine size: 475cc displacement for the Foreman ES across most model years (four-stroke, single-cylinder).
- Fuel system and electronics: variations from carbureted to electronic fuel injection (EFI) occurred within the 475cc framework, while the engine size stayed the same.
- Markets and model variants: ES models share the 475cc platform; other Foreman variants outside the ES line may feature different displacements.
In short, the standard Foreman ES engine displacement is 475cc, with differences mainly in fuel system and transmission electronics rather than engine size.
What ES means
The letters ES denote Electronic Shift, Honda’s transmission option that lets riders select gears via a handlebar switch rather than a traditional foot shifter. This feature is paired with the 475cc engine in Foreman ES models to deliver a user-friendly automatic/semi-automatic experience without changing the core engine size.
Summary: The Honda Foreman ES is powered by a 475cc engine; ES refers to the electronic shifting system, and the displacement has remained 475cc across most Foreman ES generations, with updates focused on fuel delivery and transmission electronics rather than a larger engine size.
