Honda 400EX Affordable Trail Quad Project Test 

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

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.

One of the greatest machines ever made

One of the best channels on you tube 👏

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

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.

Awesome Job as always EVAN!!!

Awesome video as always. Love it 👍🏻

Wow. The passion and attention to detail is impressive. Well done.

Good Ole days. Thanks for a up lifting video

Love it!!!

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

What year did the 400ex get reverse

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

This is a 99 Honda? She's beautiful!!

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

👍👍👍

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

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

Why didn’t you put the nerfs back on?

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.

Really bothers me the front tires are facing 2 different directions lol

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
