The FourTrax lineup covers a range of ATV models with top speeds typically between 45 and 70 mph, depending on the specific model and its configuration.
The FourTrax family includes both utility/work-oriented machines and sport-focused variants. Top speed is influenced by engine displacement, gearing, rider and cargo weight, terrain, and any aftermarket modifications. The figures below reflect common stock configurations and are intended as a guide rather than guarantees for every machine.
Typical top speeds by FourTrax model
The following estimates reflect stock configurations for popular FourTrax variants and serve as a general reference.
- TRX250X/TRX250EX: approximately 50–60 mph (80–97 km/h).
- TRX420 Foreman (420cc utility): approximately 45–55 mph.
- TRX500 Foreman (500cc utility): approximately 45–60 mph.
- TRX450R (sport/competition): approximately 60–70 mph.
These numbers are approximate and can vary with rider weight, payload, tire size, altitude, maintenance, and other factors. Always ride within safe limits and follow manufacturer guidance.
What factors influence actual speed
Several variables can cause real-world performance to differ from stock specifications. The most influential factors include:
- Rider weight and cargo load
- Gearing and final drive ratio
- Tire size and air pressure
- Terrain, surface conditions, and incline
- Engine condition, cooling, and temperature
- Altitude and environmental conditions
- Modifications (exhaust, ECU/jetting, cam, and aftermarket tires) and their tuning
For accurate expectations, refer to the specific model’s owner's manual and consider performing controlled speed checks in a safe environment.
Summary
In short, Honda FourTrax ATVs span a speed spectrum from the mid-40s to the high 60s mph in stock form, with sport models like the TRX450R reaching into the 60–70 mph range. Real-world speeds depend on model, setup, and riding conditions. Always prioritize safety, wear protective gear, and adhere to local laws and manufacturer guidelines.
