Approximately 22 horsepower.
The 1993 Honda FourTrax 300—often referred to by its model code TRX300—represented Honda’s entry into the 300cc class of all-terrain vehicles. Engine displacement and tuning were aimed at reliable performance and strong low-end torque for work and recreational riding. Official horsepower figures from the era are not always uniformly published, and different measurement methods (crankshaft horsepower vs. wheel horsepower) yield slightly different results. In practice, most contemporaneous catalogs and rider reports place the engine output in the low- to mid-20s horsepower range, with drivetrain losses meaning wheel horsepower is lower.
Model and Power Context
The 1993 FourTrax 300 used a carbureted four-stroke engine in the roughly 270–300cc class, designed for durable torque and everyday usability rather than peak speed. The FourTrax line included both two-wheel-drive and four-wheel-drive variants, sharing a core engine family in many early models.
Factory Horsepower Range
Note: The following breakdown reflects how horsepower was reported in era catalogs and common measurements.
- Official catalogs from the Honda era typically cited crank horsepower in the low- to mid-20s, commonly around 22–23 hp.
- Independent dyno tests and owner reports from the period generally align with a crank rating in the low 20s.
- Rear-wheel horsepower, accounting for drivetrain losses, is lower than the crank figure, often resulting in roughly 18–20 hp in stock condition.
Because variants, elevation, temperature, fuel quality, and any modifications can affect the figure, horsepower is best understood as a range rather than a single precise number.
Why the figure matters for riders
Horsepower influences acceleration and top speed, but for a 1993 utility-focused ATV, torque and reliability often matter more to riders negotiating rough terrain or towing. The FourTrax 300 was designed to provide steady, usable power across a broad RPM range rather than scorching performance.
Bottom line: The 1993 Honda FourTrax 300’s engine output sits in the low- to mid-20s horsepower on the crank, with wheel horsepower typically a bit lower due to drivetrain losses.
Summary
The 1993 Honda FourTrax 300 (TRX300) is commonly described as having roughly 22–23 hp at the crank, with real-world wheel horsepower somewhat lower. This aligns with its design emphasis on reliability and torque for everyday riding. For restorers and enthusiasts, these figures provide a useful baseline for performance expectations within the era’s specifications.
