Typically, a 2004 Honda TRX400EX sits in the roughly $2,000 to $3,500 range in today’s used-ATV market, depending on condition and region.
The 2004 model year of Honda’s mid‑size sport ATV remains a popular choice for riders who want a light, throttle-responsive machine that’s relatively easy to maintain. Because the TRX400EX is now about two decades old, its value is largely a function of how well it’s been cared for, how complete the maintenance history is, and what the local demand looks like. Below is a practical guide to current valuations and how buyers and sellers typically gauge worth in different scenarios.
Current market snapshot
Prices vary by condition, mileage, and what’s included (stock parts vs. aftermarket upgrades). The ranges below reflect typical asking prices seen on major marketplaces and dealer listings in recent months.
- Excellent/low hours, stock condition, clean plastics, good tires: about $2,800–$3,500
- Very good condition, minor wear, tires and chain in good shape: about $2,200–$2,800
- Good condition with visible wear, some scratches, older tires: about $1,800–$2,400
- Fair condition or higher mileage, needs routine maintenance: about $1,000–$1,800
- Not running or as a project needing significant work: about $800–$1,400
In sum, the value hinges on how well the machine has been maintained, any recent repairs, and how much work a buyer is prepared to do after purchase.
Where to check current prices
To gauge the going rate, consult multiple sources that reflect local markets and seasonal demand. Look for a mix of dealer listings and peer-to-peer platforms to get a clear sense of range.
- NADA Guides and other used-ATV valuation services for baseline ranges
- Kelley Blue Book and similar consumer-vehicle price aggregators for regional tweaks
- Online marketplaces such as eBay Motors, Craigslist, Facebook Marketplace, and regional classifieds
- Local power-sports dealers and trade-in listings
- ATV forums and owner groups where members share recent sale prices
Tip: Always compare several sources and factor in local demand. If you’re buying, try to verify maintenance history and request any receipts or service records to back up the asking price.
Inspection checklist and buying tips
When shopping for a 2004 Honda 400EX, use this quick checklist to avoid surprises and assess value accurately.
- Engine and compression: request a cold start and listen for smoke, knocking, or unusual sounds; check compression if possible.
- Frame and welds: inspect for cracks, bends, or signs of a crash repair; check for rust in the frame and subframes.
- Suspension and steering: palpate for looseness, leaks, or worn bushings; test brake function and front/rear brake pads.
- Electrical system: test starting (electric and kick), lights, and charging system; verify battery health.
- Controls and drive train: ensure the clutch/gear shifter works smoothly; check chain tension and sprockets; inspect CV joints for wear.
- Cosmetics and tires: assess plastics, fenders, and seat; evaluate tire tread and age; note any fuel leaks or oil leaks.
- Maintenance history: review service records, timing if applicable, and any recent part replacements (brakes, carb cleaning, coolant, air filter).
- Title and paperwork: confirm clear title, VIN matches, and any lien status if purchased from a dealer.
Following a thorough inspection helps you price fairly and reduces the risk of hidden repairs after the sale.
