While i don’t disagree with anything you’ve said, i think in front of everything you’ve said is NERF BARS, followed by intake, exhaust, and jetting, and tires, because the stock rears are hilarious. I purchased an 03 400ex new in 02, and the brakes or shocks have never been an issue. I freeride and track ride regularly. The brake mod you did sounds like an awesome idea, dont think ill do it, but its badass im sure. This is the first ive heard of what youve done. 👍🏻

Kawasaki had a older year 400 4x4 with a clutch and gears like a 400ex. I think it would be a fun trail atv with decent shocks and not too big and heavy tires.
Great video. First thing I did on my 400 EX was buy 450 R shocks and grind to fit.. They are a bit stiff but I have all the adjustments at the lowest settings and it's night and day over stock. I'm 200 pounds so it works out OK for me. The brakes on mine are OK for me but I can see how much rear ground clearance you've gained with the smaller rotor. Good stuff.
Front breaks on a 400ex are fine..raced 6 years with no issues. If your fast you don't use your breaks hardly at all. Just get aftermarket break pads and your good
For easy addon front shocks that don't require revalving. Use either kawasaki kfx400 fronts or suzuki ltz fronts either being resivor shocks like the trx 450r ones. But are much softer and better for riders under 200 lbs with no need to revalve. .. the dual piston front yfz450r calipers are awesome. To further improve break response. Use braided brake lines. For longer lasting stock breaks use centered metal pads. They out last the other flavors. With a slight loss of stopping grip.
Reading these comments, I have to add one my VERY BEST mod I did to my 2000 400EX. A +2" rise steering stem replacement. At 1st ,I ordered a 1", put it on and didn't like it. Sent it back and got the 2" which is the way to go for me. And understand I am 5'9 with arms from top of shoulder to end of finger at 30" 's. The tallier one was the way to go for me. The bike is much easier to turn and hang onto in the rough, and does not wear me down as quick. Just saying.
I got some elks for suspension I agree. I tried getting the larger pads for the 400ex calibers and they quit making them that dose suck but get a rear skid plate I gotta steel one the rocks chewed it up but I don’t bend anything
the front 400 ex shock s are pogo sticks lol same as the utility quad shocks with a tiny preload adjustment .. earlier Yfz 450 front shocks fit wit the same way as the trx 450r with no need to revalve them .. they get taller in the later years (i think around 2012 or 2014 and are too tall .. kawasaki 400 and 450 front shocks bolt on with out the grinding or re valving .. but the rear 400ex shock is identical to the 450r rear shock other then about 3/4 or1" shorter .. and the kawasaki ,suzuki and yamaha front brakes are a direct bolt on and all the same brand brake manufacture .. Braided brake lines make them even more responsive .. currently i have houser +2 arms and +2 stem .. with 18."tall fox podiums from some donor polaris quads .. and a shock mount bracket i made .. a decent set of pegged Nerf bars 9 the dual caliper front brakes n braided lines and a YZF 250 FCR carb n Duncann full exhaust ..
Which Pro Taper bar is that one? I bought a seven-eighths one with CR bend and I had to install a 1 inch rise from it, but I really like that look of not having a crossbar on it.
Why do you not run a swingarm guard? I have an aluminum plate on my 2005 and its bouncing off rocks all the time it seems that would otherwise be bashing my swingarm and or chain and rear rotor.
I think the only thing that should have came factory is the battery starter relay and rectifier and wires should have all been mounted inside the airbox so that it doesnt get wet.
There are way better shocks to put on that bike, and you don't have to do any grinding. I've been riding for 35 years, and trust me, those things fly, and I'm not talking about on the ground.
Carpets World I’m also assuming the 450 caliper is just way better than the stock 400EX caliper because my 400’s caliper is currently frozen and I was thinking about doing this but I was curious about how worth it it was
you side the year on frount what about back ? if you can tell me if this well work on a 01 400ex. I'm about to trade my blaster for a 400ex got a buddy that loves my blaster and wants to tr and so I'm down . so if you could break it down for me so I can make these breaks work it would help I do a lot of train riding and hate shit breaks . thanks for the help brother safe riding

Love the 400EX and wish they had made in 4wd for those of us who want a sport quad that live in harsh climates.
27Zangle try a scrambler or trailblazer if you want a mix between a utility quad and a sport quad

Dude, I love this video. Love the cost effective and budget friendly upgrades. This is perfect!!
You could also change the spindles to a 2006+ trx450r and then use the dual caliper trx450r front calipers ... if you wanted to keep it all Honda.
Just picked up a 03 trx400ex and will definitely be doing these mods. Thanks for the info.

Nice. Setup now u got me thinking.
awesome mods man..
Great video very helpful
Good info thanks-
The 400EX is a great trial riding quad.
450R is has high compression, awesome track bike, dessert. Just not very reliable

So I guess the moral to the story is buy a Honda 450R
MoToToYz lol really. Theres a reason why i have both. Lol. And 400ex shocks are trail shocks as 450 shocks are race

You need to do a video on how to do the conversion
Good video
My stock front brakes 14 years old a great they haven’t really worn at all it seems like
Same with my 03.. Never had a problem
Sounds like the guy doing the video does a lot of stoppies
Dual rate shocks with resivoir, removable clutch cover and a kill switch tether.
The front yfz swap did u get the entire hub or did u just get the caliper and rotor. Jw if the wheel pattern will b the same
hmongwild just the caliper and brake pads. That's all you need
Which Pro Taper bar is that one? I bought a seven-eighths one with CR bend and I had to install a 1 inch rise from it, but I really like that look of not having a crossbar on it.
What year trx450r rear break setup do I use to swap on to my 04 400ex
You can get rear skid plates for like 120 bucks instead of doing a whole caliper conversion and not worry about your sprocket or caliper being damaged
The caliper conversion has nothing to do with the skid plate and ALL to do with having dual pistons instead of the stock single...
@@travisbarnes7768 he's talking about the rear one
4th should be the rear carrier bearing upgrade
The rear brake mod, eliminates the brake stay?
This work on the 2002 for the yfz break upgrade?
Did the yfz shocks lower the front end any?
Why do you not run a swingarm guard? I have an aluminum plate on my 2005 and its bouncing off rocks all the time it seems that would otherwise be bashing my swingarm and or chain and rear rotor.
Those guards kill ground clearance too. I prefer those bolt through sprocket guards and an under rotor guard.
1 mod, upgrade calipers. :p
My 1999 all stock all original . Never had an issue with the 32k hours it has on it . Oil change every 18 hours . Runs and rides like new .
Get a new Yamaha YFZ450R while you can. Brand new from Dealer. I did! #1 sport quad ever made.
Agreed. ..Leave It Stock !!! There's Never a Good Reason to Frankenstein an already Great Quad !!!
No
All these mods but still no Nerf bars...
Maaaaate
Yeah no $h1t! You are simply lazy if you are riding without nerf bars.
Nerfs are for people who forget where footpegs are..plus they get in the way on trails
@@kennys501 Of course it gets in the way. In the way of your FOOT as it falls to the ground and UNDER the rear tire 😂
@@jayryan7473 you'll be fine with heel guards
What about the disk?? And 450r quad or bike ?
I think the only thing that should have came factory is the battery starter relay and rectifier and wires should have all been mounted inside the airbox so that it doesnt get wet.
My dad just ordered me TRX450R shocks the stock ones would beat my ass on trails I would bounce around and shit
Do you think a 400ex is a good starter quad for a 16 year old that has little experience on a quad and a pit bike.
Yes
Do you use yzf quad calipers or the dirt bike yzf
Scott Speck yfz quad front calipers
would this fit on a 07 250ex?
I got a 400ex now :)
West Coast Machines I don't believe so.
Carpets World ok thank you for the advice :)
@Silver Dynasty what are you getting at?
I think 400ex stocks great just exhaust and jets and im happy
Bike looks hardly ridden...How did you get her so clean???
Wash it
It actually drop a tooth, bumper and skid plates all the way through
The intro looked like something from a horror movie
There are way better shocks to put on that bike, and you don't have to do any grinding. I've been riding for 35 years, and trust me, those things fly, and I'm not talking about on the ground.
I cant seem to get the pipes slid onto the head... considering taking off the oil tank now
I have never worn out a break pad since 2013
Did you need to get any new bolts to do the rear brake mod?
Nope

Michael Tremblay any year trx 450 rear brakes should work. As for the front calipers I believe it is 04-12 yfz 450.
Might as well get a YFZ
Only an efi
You mean 2004 400ex last year with no reverse THANK GOD lol
Last year for the bug eye, and no reverse. But who needs reverse? Lol

Whats the difference between the 01 to the 04
Nothing
The stickers on the side changed a little bit.
The shocks is cool but u wreaking it bu grinding the mount not a good idea
Noice I have 2005
Year of EX anyone :)
Who uses brakes? I put my mods into the engine performance..lol
Or u just get a skid plate instead of new rotors
I suppose that would work if you're cool with only having a few inches of clearance
you need new tires....
Why? They are fine.
Wanna be 450r owner
More like 450r, 250r, and 400ex owner, but want the 400 to perform like the others.
Haha jealous
why not just buy à 450 ?
Julien Plante 400 is better for trail
Mine is 440 boared
