How fast does a Honda FourTrax 350 go?

Most stock Honda FourTrax 350 models top out around 45–50 mph (72–80 km/h) on level ground, with 4×4 versions generally at the lower end and 2WD variants sometimes edging a bit higher. Real-world results vary with tires, condition, and terrain.

What “FourTrax 350” refers to

Honda has used the FourTrax name on several 350-class utility ATVs over the years. Depending on the year and trim, the machine could be 2WD or 4×4, carbureted, and almost always geared for work and trail reliability rather than outright speed. That’s why reported top speeds cluster in a relatively narrow band across variants.

The bullets below outline the main FourTrax 350 families and the typical top speeds owners and testers see from stock, healthy machines.

• 1986–1987 FourTrax 350 (TRX350, 2WD): commonly around 50–52 mph when stock and well-tuned.
• 1987–1989 FourTrax 350D Foreman (TRX350D, 4×4): typically about 45–47 mph due to 4WD driveline and utility gearing.
• 2000–2006 FourTrax Rancher 350 (TRX350TE/TM/FE/FM): usually 45–48 mph; many are rev-limited in the high-40s from the factory.

While the engines and frames differ by generation, the utility-focused gearing, tire choices, and conservative rev limits keep their peak speeds broadly similar.

Factors that affect real-world top speed

Two otherwise identical FourTrax 350s can post different top speeds because small changes in setup and conditions make a noticeable difference. Consider the following influences when comparing numbers.

• Tires and wheels: Aggressive mud tires, larger diameters, or heavy wheel/tire combos can shave 2–4 mph (or more) off the top end.
• Mechanical condition: Carburetor tuning, valve adjustment, spark quality, compression, wheel bearings, and dragging brakes all affect peak speed.
• Load and environment: Rider weight, cargo, headwinds, elevation, temperature, and trail vs. pavement surface change results.
• Drivetrain setup: 4×4 engagement and differential type add drag; some models also have rev or speed limiters that cap top speed.
• Aerodynamics and accessories: Racks, boxes, windshields, and even rider posture can cut a few mph off the peak.

Because of these variables, any quoted top speed should be treated as a range rather than a precise figure for every machine.

How to check your ATV’s actual top speed

Many FourTrax 350s lack a calibrated speedometer, and wheel-driven readings can be thrown off by tire changes. For a trustworthy number, use simple tools and repeatable methods.

1. Use GPS: A dedicated GPS unit or a reliable smartphone GPS app gives the most consistent speed readings.
2. Make two-way passes: Run in opposite directions on the same stretch and average the results to cancel wind/grade effects.
3. Account for tires: If using a speed sensor tied to wheel speed, ensure the system is calibrated for your exact tire size.
4. Prioritize safety: Choose a flat, open area, wear proper gear, and avoid traffic or obstacles.

Documenting conditions and repeating the test after maintenance can also help diagnose whether your machine is down on power or running as expected.

Can you make a FourTrax 350 faster?

Modest improvements are possible, but these ATVs are designed for durability and torque, not high top speed. Any changes should be weighed against reliability and safety.

• Bring it to factory spec: Fresh air filter, clean carburetor with correct jetting, new spark plug, proper valve lash, and no dragging brakes often restore lost mph.
• Optimize rolling setup: Correct tire pressure and switching from heavy, aggressive treads to lighter, trail-oriented tires can recover a few mph.
• Electronics and gearing: Some Rancher 350 variants can see small gains with CDI or limiter changes, but results vary and may risk engine longevity; the shaft-drive layout limits easy gearing swaps.
• Reduce drag and weight: Removing bulky accessories or windshields helps slightly, though gains are typically small.

Even with tweaks, most FourTrax 350s remain in the mid-to-high 40s mph. Brakes, suspension, and chassis are tuned for utility speeds, so ride within the machine’s design envelope.

Summary

Expect a stock Honda FourTrax 350—whether an ’80s TRX350/350D or a 2000s FourTrax Rancher 350—to reach roughly 45–50 mph, with 4×4 trims and aggressive tires trending slower. Actual top speed depends on condition, setup, and conditions; verify with GPS and focus on maintenance and safety over chasing extra mph.

What is the top speed of the Honda 350 Fourtrax?

With a top speed of only about 40 mph, the 4×4 Foreman isn’t an open country flyer, but is attractive in many other ways.

How fast is a Honda Fourtrax 300?

A Honda FourTrax 300, which is an ATV, can typically reach speeds of around 50-55 mph (80-88 km/h). However, factors like terrain, rider weight, and specific model can influence the actual top speed. Some users have reported hitting 55 mph on a FourTrax 300, while others mention hitting the rev limiter around that speed. 
Here’s a more detailed breakdown:

• Typical Speed: Expect a top speed in the range of 50-55 mph (80-88 km/h). 
• Factors Affecting Speed:
  • Terrain: Off-road terrain will naturally reduce the top speed compared to a flat, paved surface. 
  • Rider Weight: Heavier riders may experience slightly lower speeds. 
  • Model Variations: There may be slight differences in top speed between different years and specific models of the FourTrax 300. 
• Limiter: Some riders report that their FourTrax 300s will hit a rev limiter or “float the valves” around 55 mph, limiting further acceleration. 
• Not Designed for High Speed: While the FourTrax 300 can reach a respectable speed, it’s important to remember that ATVs are primarily designed for off-road capability and utility, not high-speed racing.

How fast does a Honda 300cc go?

The top speed of a Honda 300cc motorcycle varies depending on the specific model, but generally falls within the range of 85-95 mph (137-153 km/h). For example, the Honda CB300R is listed with a top speed of 90 mph (145 km/h), while the Honda Rebel 300 is reported to reach 95 mph under ideal conditions according to a YouTube video. The Honda CRF300L is typically reported to reach a top speed of around 75 mph (121 km/h), but some owners have reported achieving speeds up to 85-90 mph on a YouTube video. 
Here’s a breakdown by model:

• Honda CB300R: 90 mph (145 km/h) 
• Honda Rebel 300: 95 mph under ideal conditions according to a YouTube video 
• Honda CRF300L: Around 75 mph, with some owners reporting up to 85-90 mph on a YouTube video 

It’s worth noting that top speed can be affected by various factors including rider weight, wind conditions, road conditions, and any modifications to the motorcycle.
