How Much a 2006 Honda 400EX Weighs
The 2006 Honda 400EX (officially the Honda TRX400EX) weighs about 409 lb (186 kg) in curb/ready-to-ride trim and roughly 374 lb (170 kg) dry, without fuel and most fluids. Those two numbers are often cited interchangeably, but they represent different measurement standards and can lead to confusion when shopping, comparing, or transporting the quad.
Understanding the Published Weights
Manufacturers typically provide more than one weight figure. For the 2006 TRX400EX, the commonly referenced figures are a dry weight around 374 lb and a curb (wet) weight near 409 lb. The curb figure reflects a machine you can ride off the trailer—fluids and fuel included—while dry weight is measured without fuel and certain fluids and can understate what you’ll actually move or ride.
Why You’ll See Two Different Numbers
Because riders, sellers, and spec sheets don’t always use the same standard, it’s common to see both weights quoted for the same quad. Honda updated the 400EX’s styling and added reverse for the 2005 model year, and the 2006 model carried essentially the same platform and mass, so the weight figures remained in the same range.
The following list explains the most common weight terms you’ll encounter and what they mean for the 2006 Honda 400EX:
- Dry weight: Approximately 374 lb (about 170 kg). Measured without fuel and, in some cases, without certain operating fluids. Not representative of real-world, ready-to-ride mass.
- Curb (wet/ready-to-ride) weight: Approximately 409 lb (about 186 kg). Includes fuel, oil, coolant, and other required fluids—this is the practical figure for transport and riding.
- Accessory impact: Aftermarket parts (skid plates, nerf bars, larger tires/wheels) and cargo can add several pounds beyond curb weight.
Keeping these distinctions in mind will help you compare listings accurately, plan trailer and tie-down needs, and estimate performance differences tied to mass.
How This Applies in Practice
If you’re hauling or calculating payload, use the curb weight of about 409 lb, since that reflects a running machine with fuel. If you’re comparing factory specs across models or looking at power-to-weight ratios on paper, you might see the 374 lb dry figure cited—just remember it’s optimistic for real-world scenarios.
Tips for Verifying Your Specific Quad
Because decades-old machines may have modifications that change weight, you can take a few steps to confirm what you’re working with.
- Check the owner’s manual or archived Honda spec sheets for the 2006 TRX400EX to confirm factory figures.
- Account for fuel: a near-full tank (roughly 2.6 gallons) adds around 15–16 lb.
- Weigh the quad on a platform scale if precision matters for transport or competition tech inspection.
A quick check against documentation and a scale reading can eliminate guesswork, especially on machines with added protection, storage, or performance parts.
Summary
The 2006 Honda 400EX weighs about 409 lb (186 kg) curb/ready-to-ride and roughly 374 lb (170 kg) dry. Use the curb figure for practical planning—transport, trailering, and ride-ready comparisons—and keep in mind that accessories and fuel level can nudge the real-world number slightly higher.
Are 400exs reliable?
The 400EX is one of the greats, up there with the Yamaha Banshee 350. Where the Banshee has an extraordinary powerband that can almost suck the vehicle right from under your hands, the 400EX has reliability and ease of use.
