1975 YAMAHA MX400

[@CK-mf6du]

It's mind boggling to get to see this guy rip around these old classics. Truly get a feel for every one of these bikes. Could only imagine getting an opportunity to work there!

[@StoneyBus]

I own one of these earth shakers, honestly you can feel the ground. My first big-bore-2-stroke -experience was 1975-76 on a mx360, a kid from Hawaii moved to our apartments, his dad was U.S. Customs. His dad told me if l could get it running l could ride it til it sold, scared me, however, that fear drove my desire to harness/control that power. It's like opening a door, squeeze more throttle & see what is behind the door, under the bed scary, it was amazing. Fearful fun to the fullest, send it did l way back then.

Such a nice bike. Ahh the old days. I was too young for this big of a bike but the 100/ 175 were as good ! Love seeing these roll thru. 🇺🇸

[@rogerdittus2952]

Had one in the late 70s, so did at least two of my friends. Don't off-road any longer but the old mono looks like such a low rider now compared to the last dirt bike I had (2016 KTM xcw 250). That old bike couldn't even roll over many of the trails current dirtbikes take fir granted, but it's really pretty!

[@albertsammut433]

I remember these beasts back in the day..If you couldnt afford the latest best and expensive big bore YZ360B offering from Yamaha then this was certainly the next best machine for you to race on..This 400 and the 250 were everywhere going back 47 years ago😯😯

[@stevestewart6287]

A friend of mine had that bike in 1975, I was 15 years old and I had a Hodaka 100cc Dirt Squirt. The engine on those bikes was great, but the suspension sucked, the mono shock only had about 4 inches of usable travel back then, and it would bottom out on even a small jump. And the front shocks were not much better, they only had about 5 inches of usable travel. But that motor was kick ass, it had a lot of power, ran forever, the powerband was awesome, and it was bulletproof. I rode it many times, and it was really fun, as long as you did not hit any jumps with it.

[@darren_clark]

Love seeing the old bikes. Thanks!!

[@randycarpenter3663]

Love your dedication to the frame rails….

[@wanble3]

I owned the mx400b when it was brand new I wish I never would’ve sold it! I loved it

[@andrewbecker3700]

DT400 was also a great bike. Had a few and when they're modified properly they can boogy. I used 650 twin kickstarter arms.

[@phantomshtter]

That peachy beast sounds absolutely gnarly. I'm a blue blood at heart. Typically hate the sound of 2 strokes myself but that's a different animal right there!

[@johnpatrick3866]

Very capable and beautiful bike. Thank you Kaplan for another great video!

[@ronniemashburn1347]

Luv how y'all go with the original Handel's the distinctive to them old schools way Kool bro

[@markterence3689]

I love the shape and design of the exhaust including the stinger.

[@codjh9]

Bought one new when I was 16. Unless my bike was an exception, the motor is NOT bulletproof. Some of my gears stripped after a while - I think the bike had too much power for the gearbox, and I heard about others having the same problem, but I did love the bike.

[@markmenzies4218]

what a beauty! love that classic 2 stroke sound.

[@HarborDavidson]

I still have one of these, they're so fast bikes, can ride it like a MX or hammer it like a YZ. If it had good suspension it would be good.

[@offgridliving4128]

I also had one of those as a kid. Use to ride it at the Oregon dunes. Had to make a spacer to lift the rear so the paddle tire would snag on the rear fender at full compression.

[@kennytree8801]

Thanks. That sound... sounds like rocks getting thrown in the tail pipe, love this video

[@murrayminimotors1674]

Glad to see u made it back safely and right back into the 🏍!! Sweeeet!!

[@cameronshine3465]

that looks like a 400 MXB , I had one in 1977, i was only 16 and i weighed not much more than a feather. The best bike i ever owned. O yes they can move.

[@scottreynolds3148]

First new bike I owned paid 1450 out the door great enduro bike still have owners manual

[@rt2255]

Street tires low front fender, rear street tail, add stator lights clip ons, best street fighter bike ever

[@kingkong81icloud]

Cannot believe you not got a DT125R yet , good bikes hard to find, there’s a load in France I think, an a few in the UK but I liked them more than YZs, I had 4

[@cameronshine3465]

That bike is so so so fast, i mean it. The good man showing off this bike is not showing what this bike can really do, Its so quick.

[@skatedd2451]

That's a beautiful looking bike

[@ronniemashburn1347]

First year the full floater suspension way badass

[@sporty05]

Great video and bike Cap'n, I almost hate to watch your videos because it makes me want bikes I can't afford. :)

[@АнатолийПранович]

Класный мотоцикл, я бы купил бы У вас, или приму как подарок 👍👍👍👍👍👍

[@stephenmacdonald912]

I wouldnt wanna get stuck in the throttle cable.. nice bike

[@Nudnik1]

Cool era . First monoshock design.

[@phoenixarizona8441]

This bike was built to run with the cr500 I had a 75 dt175 and dt400 a few years later

[@johnhansen7499]

It says that this model has basically 39 hp, and that pretty much great! A beautiful bike that is probably already sold.

[@bartbullock9742]

Yup... I had a brand new one... I remember it vibrated a lot

[@kennyrichard2971]

Wow thinking of The Incredibles sound of 35-40 vintage big bore at the starting gates This bikes tail don’t wag but Front fender is saying bring it on

[@keithhawkins7039]

Fresh crisp Yamaha sound.

[@sonnyseabury4051]

I always wondered what was the difference between the MX's and the YZ's.?

[@larrynorsworthy8582]

I just typed the same question. Let me know if you get an answer. Thanks.

[@sonnyseabury4051]

@@larrynorsworthy8582 Will do, Brother.

[@keithdawson4804]

Me too! I had assumed the MX model range pre-dates the YZ (which I assumed started from 73, same as RD, TX, DT, TZ, etc) BUT this is already a 400, and MY 75/B comp decals.. and first open class YZ was an earlier 360cc.

[@luisarreola9420]

I had a 1976 YZ 250 C and a friend had a MX 250, there were no difference, same motor, same parts, only difference was the paint scheme YZ had the bumble bee color and the MX was white and red. The YZ had the canister forks, the MX didn’t.

[@elcapitano1972]

Music! 😍 sounds lumpy. 💪🏼🎨🤤

[@carloscantori4114]

Una maquina hermosa

[@ronniemashburn1347]

That's a beast for real !

[@rt2255]

Put that motor in more modern 250 chassis and you got a beast that handles.

[@rt2255]

Or better yet with low suspension, convert to street bike lol 400 2 stroke with lights and grippy tires would be a street racer for sure. Eat huge 4 stroke street bikes up to 90 or 100mph with street gearing and low weight of that thing

[@ronniemashburn1347]

Big bro yr so lucky you HV rode everything man you tell how much power that beast has gt cuz yr big o boy I CD tell it pull wheelies nyhn but throttle I've been courious do you feather that back brake or I bet you keep that rt foot whr you ND it just in case ?

[@jackizuzu7289]

The bike is a 76 at the newest 76 was the first year of mono...it may have been manufactured in 75 but that bike is a 76 77 model

[@robertmccool1543]

Not really, they did make a few 1976 possibility but it was the exact same bike however all yellow. This was sort of a pre 75 release. Remember, Yamaha had a few different models at this time. The super rare yz250 ( strap on tank ) twin shock semi factory bike the public could buy, then some yellow mono shock yz's that were yellow not the factory bike, had a square cylinder head. The 77 bike had the kyb air chambers on top of the fork tubes. 78, all new frame design.

[@jonnysuperglide]

Sweet bike right there oh my

[@markmoore1819]

I had the same one which i still had it

[@bretthoffman2128]

I Thought You said it was a Wheelie Machine? Those were kinda tame

[@zackiaryruddick701]

Kaplan makes that bike look like a peewee 40 🤣🤣🤣💪

[@larrynorsworthy8582]

The mx and yz existed at the same time. Can someone explain them? Differences?

[@MrVnssbt1]

Classic bike very nice but please PUT the correct length cables way to long looks abit funny 😄

[@kenhall2254]

I had a brand new one, if it hooked up in first or second gear it would leave you sitting there. It drug me first to the finish line many a time. More brawn than skill, just point and hang on.

[@davidgoodrich4745]

Akront rear rim incorrect . I still want it.

[@sambuvca22]

that things great!!!

[@7x779]

how does this compare to the dt400?

[@ronaldspins]

Different strokes for different folks ............

[@raymccormick5936]

Man does that sound nasty at idle

[@jasonkennedy1670]

looks sharp

[@PetterIvarsson]

3:00: strange, two spark plugs and only one connected. Why?

[@keithdawson4804]

Second hole can be used for decompressor valve. Spark plug simply filling the hole.

[@PetterIvarsson]

@@keithdawson4804 aha, clever

[@aryfitriaji9620]

❤ vintage dt

[@powamoto]

Classic

[@docfischer7291]

A friend of mine had one as a pit bike at one time, it always sounded pissed off …. Like a dog on a leash with its eye on something waiting to be released.

[@bobg1219]

Winner!

[@barasentosa5765]

nice bike

[@randycarpenter3663]

Awesome

I’m about to buy one of these off mp for $1,000 and restore it

[@cameronshine3465]

i was only 14 years old when i had a MXB 400 and i weighed as much as a feather , that bike can beat a 900 Kawasaki, i know because i raced one.
