Honda 400EX Affordable Trail Quad Project Test

[@ATVonDemand]

Links in description for the three part build. Building this 400EX trail quad project was a lot of fun and showed us why the machine was so well received when it debuted back in 1999. While the end price was a little higher than we expected we feel the machine was well worth the investment and was still far less expensive than buying a new machine. We hope you enjoy the video.

Probably the most do it all sport quad of all time. Things are awesome not to mention dang near indestructible. Honda is really letting the community down not producing new ones. I know personally I’d take on more debt for a modern 400ex

[@ATVonDemand]

When we both!? I could definitely go for a fresh fuel injected 400EX.

The z400 was a little better

@@soundnessofmind7196no it wasn’t lol

[@soundnessofmind7196]

@@Nunya-gk9fr yes because it was liquid cooled, so it ran cooler and had better suspension. Lil more power too stock

Thanks for making our day!

Awesome Quad . We need more and more from you guys ! We are glued to your channel :)

[@ATVonDemand]

We have a couple more sport quad videos filmed and ready for editing. More to come.

[@OdysseyOffroad]

That machine looks great. Nice refresh! In my opinion that's what's missing in the whole market. The 400 class was perfect for any rider, skilled or new.

[@ATVonDemand]

Adequate power and great handling. It's the perfect machine for many.

[@blayneerwin9276]

One of the greatest machines ever made

It is really a great all around performing sport machine.

Awesome video as always. Love it 👍🏻

Really glad you enjoyed it. We really enjoy playing with sport quads. Wish they were more.

[@johnnygt6039]

I remember my first time seeing a 1999 Honda 400ex. Nothing was like it at the time! Now, this project cost does compete with much newer (still used) Raptor 700's though, food for thought.

[@ATVonDemand]

True.

[@brainstain22]

Man I can't wait to see what else this quad gets. Ready to see it prepped for a race. I would also like to see it raced. Awesome build.🤘

[@ATVonDemand]

@@brainstain22 Thank you! It's a fun machine. I am sure we will do more with it.

Good Ole days. Thanks for a up lifting video

[@ATVonDemand]

So glad we could help!

[@chaseharcourt3807]

Question did the new throttle and clutch cables make the throttle and clutch any lighter? Is it worth it

[@ATVonDemand]

Hit me the pull a little lighter and smoother. It's way less expensive than having one break on a trail ride and ruin your weekend.

[@mitchtavio]

Super cool machine. I would’ve put added a slip on though. I love the bug eye 400EX’s

[@ATVonDemand]

More to come.

[@jacksonhammersmith]

Why didn’t you put the nerfs back on?

[@ATVonDemand]

Great question. The way they installed they would not bolt up with and skid plate.

[@joeyboy3209]

Is it really affordable if you put that much into it for the average person? I wanna just buy it and ride it.

[@ATVonDemand]

And you could do that if you don't mind riding an ATV with some bent parts and the bearings that are going bad that will only continue to degrade and inevitably wear out other parts. Or you could spend more on an ATV that needs nothing and pay more for it. We obviously spent some money to protect the machine. We would do that for any new or used quad. If you don't mind smashing your lower frame rails flat that's up to you. Bottom line is, this this sport is not cheap. But this AYV, upgrades and all costs less than the mountain bike I am currently riding for prospective

[@foxx8296]

Очень хорошо получилось. Где увидеть список использованных запчастей? я бы хотел их купить для своего trx400

[@DirtbikerG63]

What year did the 400ex get reverse

[@onewisedre]

Could I put a set of used trx450 front shocks on pretty cheap would have been a way better Improvement over the stabilizer and the handlebars

[@ATVonDemand]

Compared to the handlebars, maybe. Better shocks will not take the place of a steering stabilizer. They do two different things

[@onewisedre]

@@ATVonDemand I just meant dollar per dollar the trx450 front shocks would of been a better decision on a budget quad build to improve the handling. I'm well aware of what a steering stabilizer does lol. You just seem to waste money in the wrong spots on this build.

[@speedfreak8200]

I highly recommend STEDI C4 spot pods (Amazon) mount low on front bumper.... I can ride highway speed no problem. Bought my 400EX brand new 2001 runs like a top never been apart. Rotella T6

[@ATVonDemand]

@@speedfreak8200 You're proving the reliability of the 400! It's not how expensive your oil is.It's how often you change it

[@Charles-gh4hu]

Honda has always been the innovator for example the atc 250r atc 200x and 350x and then the 400ex and for a brief run the 700xx..the fastest quad ever produced

[@ATVonDemand]

@@Charles-gh4hu Respectfully the700xx It's not the fastest quad ever built. It's hard for us to be honda Fan boys when they abandon our sport for the second time for over a Decade.

[@Charles-gh4hu]

@ATVonDemand wow that really sucks. By the way what is the fastest atv ever produced?

[@Swindy1794]

I had a 400EX years ago… I’ll give it a yes and a no. When it ran, it was a great bike…. But I had no reverse and then cold weather. It was hard to start…. Not to mention typical Honda cold blooded as hell… sold it and bought a utility 4 x 4

[@ATVonDemand]

No machine is perfect. Overall it was a good one though. Hope your enjoying the 4x4.

[@brianfl33916]

Old reliable. Wish Honda would get back in the game and bring back at least 1 quad. A fuel injected 500cc that takes the reliability of the Raptor and handling of the YFZ into one reliable package would be fantastic and sell like hot cakes. I just don’t see Honda doing though. EPA regulations are getting tougher and every manufacturer seems to be sticking to the high margin SXS market.

[@ATVonDemand]

I think you nailed it on all accounts.

[@erichemmelgarn4623]

Why not just use the same engine that they are using for the 450we dirt bike engine? Just make minimal changes and it’d be fine imo

[@brianfl33916]

@@erichemmelgarn4623 that could be an option but most quad riders are trail riders. The Raptor 700 is low end torque engine that doesn’t require keeping a certain rev range to be happy. It’s a good everyday quad. I just think 700 is way overkill for most people. The 450 engines are basically what people race and have totally different characteristics. The YFZ and Raptor are different beasts. Maybe Honda could utilize the NX500 engine.

[@erichemmelgarn4623]

@@brianfl33916 I don’t know much about that engine. I just wish they would make a new one. A 500 with reverse would be cool.

[@brianfl33916]

@@erichemmelgarn4623 I don’t either. But when Honda made their 700 sport quad they basically used an engine from one of their motorcycles. That’s why it was so quiet.

[@reggiexp69]

sucks yamaha never made a 400cc quad.. like honda did or suzuki did.. like its yamaha warrior/raptor 350, then honda trx400 then suzuki ltz400.. for good trial quads but like wish yamaha used a 400cc engine of what ever moto/trail bike they had into a quad... just finished the video 3k ? the quad cost you 3k? holy shit honda trx400ex (not road legal so no papers) are 2000€ here and i find that expensive cause they are no wildly commun not like suzuki ltz400 you can get around 2500 -3200€, and road legal model with licence plates 4000€ ish i tought trx400ex cost 1500$ in most of america? 3000$ seems hella expensive for something u needed to replace so much stuff... ah oki yes you can find them for less, makes sense but seen price are different in every region. texas or new york will have complet different prices.. (like mike sabo and 2vintage) mike sabo bought a honda trx250r in not mint condition it cost him like 4k or more i forgot it was like 1000$ more then 2vintage got his. while 2vintage bought 2 fo them who ran great and were fully equiped for less

[@ATVonDemand]

A similar machine could probably be found for around $2,500 If you shop for it. If we put this back on the market as is Now that it needs nothing we would expect to get around.$3,500 -#4,000 for it. You rarely get out of a machine in dollars.What you put into it. However in fun we think we'll get every penny back out.

[@reggiexp69]

@@ATVonDemand yeah i see, i always tought quads are cheaper in the usa since there are way more common, but one thing i noticed most quads i see in the usa have still stock tyres, i almost never seen a quad in france for sale with stock tyres they are all changed. so maybe they have less hours in on quad in the usa. always odd have different things are. some quads seem to be cheaper in france but some are clearly cheaper in usa. but you guys did a great job making it look almost like new and making a nice personel machine to have fun for years.
