The Honda Foreman first went fuel injected in the 2005 model year, with the TRX500FA Foreman 500 as the initial EFI model.
This article explains the timing of that transition, what it meant for the Foreman lineup, and how EFI has influenced performance and maintenance for owners over the years.
Timeline of EFI adoption in the Foreman line
To understand the change, it helps to look at the first EFI Foreman and how the technology spread through the lineup.

The 2005 launch is widely cited as the starting point for EFI in the Foreman series, with subsequent years expanding EFI across later engines and trims.
What EFI meant for Foreman riders
Electronic fuel injection offered noticeable benefits over traditional carburetion, including easier cold starts, smoother idle, more consistent power delivery, and improved fuel efficiency. EFI also helped with emissions compliance and overall reliability in varying weather and terrain conditions.
Modern Foreman lineup
Since the initial EFI rollout, Honda has shifted much of the Foreman range to electronic fuel injection, with newer 520cc variants and related trims typically featuring EFI as standard. Availability can vary by market, but EFI is now the norm across the active Foreman lineup in many regions.
Summary
The Honda Foreman’s move to fuel injection began in 2005 with the TRX500FA, marking the start of a broader shift in the lineup. Over time, EFI became standard across most Foreman models, delivering easier starts, smoother performance, and better efficiency for Honda’s flagship utility ATV.
