[@cameronshine3465]

i use to have one, i was only 16 years old, 1976 . the best bike i ever owned and ridden

[@raysmetaltracks6782]

Man, back when I actually knew how to work on bikes... Brings back memories. Thank you!

[@EL-zo6iy]

Handcuffs, gun, and werewolf sideburns! Live it baby! Live it!

[@gregdye5691]

Bad ass dirtbike.Bought one of these brand new right out of high school in 75' and went motocross racing. Great memories , thanks.

[@larrrevenga49]

Love the sound . I raced a 74 Mx 250 in FL. Then moved up to 77 Yz 400D great video . That Mx 400 is a Beautiful bike .

[@RicardoValdes-r6w]

Thank you Kaplan for showcasing such kick ass Yamaha. Amazing bike with the sound and power I love of a 2 stroke. Great video and work you all do. !!!

[@4T5Scott]

I can proudly say I own one of these. But mine was bored out to the max and it’s insane to ride. No joke you can sit on the gas tank and it will still ride wheelies. Long live Yamaha power :)

[@jerrymarcum9981]

Ken can really make that bike roll! So fun to watch.

[@PRO4XKEV]

Vintage bike, drum brakes, I love it.

[@dr.hugog.hackenbush9443]

Drum brakes = terrifying if you need to stop.

[@ndanieltx]

Lots of 2 stroke pwr and iffy brakes is a perfect summary of the 70s 😅

[@DOC-Jake-]

Another stunner ! Just love seeing all these blast from the past ! U can’t even beat them ! Thanks u guys ! 🇺🇸

[@dannywilmoth6402]

Thank y’all for bringing back my memories of my old Dirtbike years and love you exercising your Second Amendment Wright love the side arm.

[@richardmorris7063]

A mans motorcycle there. Time machine....Ken you've done it again.I'd love to come up from Tampa to see first hand what an amazing preservation you've done there,at the compound & w/the time machines you've reserve dated is important to a lot of people.

[@Maga4Lyfe]

I remember my cousin had a mx 80. Gosh that was a blast to ride along with our honda qa 50's.

[@gardeningplus7271]

I had one in 1976 mine had two spark plugs one was spare on cylinder head beautiful bike you took me back now i have to call my old friends,5*

[@sherf2654]

First year for the monoshock and a beautiful example of an iconic big bore!

[@ronmangano9094]

It's a Webco head. Stock was a radial finned similar to DT400.

[@scottreynolds3148]

Great bike bought one new $1450 ln 75 great enduro cross country bike

[@jamesmihalcik1310]

I have one in the barn. I haven't ridden it since 1997. Looking forward to getting it going again. Pure power, well balanced. Could pick up the front end in most gears if you opened it up. Pleasure to ride, never noticed the muffler sound, it was always behind me :) Thanks for rekindling the desire to fly!

[@derrickzenner9300]

That's one of the coolest bikes ever

[@jethrox827]

I remember seeing A grade mx riders push these things to their max. There was also a yz360 mono shock around this time too

[@jasonrutherford1722]

Beast mode Captain love it !!!

[@jakebsowders357]

I don’t know if I actually ever seen a bike like that but it looks like it would rip someone’s arms off , that bike is in exquisite shape !!!!!

[@carlospuckett3161]

You have some really nice bikes.

[@danielarney9729]

45 years old and is in original moto condition. This bike is going to out live us.

[@ianmangham4570]

Wow, such nostalgia, such OH YEAH

[@tysons2ndchannel592]

This bike is Fast 👍🏆🥇🏁

[@timdryden3778]

i had one, it was fantastic. wish i still had it. far better at everything than the yz400f i replaced it with.

[@posniknelb6114]

Must of been a complete brute back in the 70s,still is now,stunning.

[@ClintL63]

I had one in 84 or 85; it had SO MUCH POWER!!! I dont think I ever sat on the seat, as i was always standing and leaning up over the handlebars!; whenever I would let somebody who could RIDE a bike, they would beat everything!!! around!!! ; I couldn't handle that bike; it beat me up; I only had it for just one summer; I sold that abusive SOB, but WOW! The POWER!!

[@Principlesofpleasure]

So jealous it’ll be a dream to have one 2 stroke I go to work watching a video of you on the sexy red rocket(CR125R) 🔥🔥🔥 and come home to see this vid of this beast 😍 if I ever hit the lotto I’m buying me and my pops one ,he’s getting older but he use to shred when I was a kid . we never got to ride together ,goal of mine for sure .

[@stimpacat]

That bike is a ripped...i love the vintage bikes like my dad 1979 cr250 Elsinore it's a monster

[@menditman2004]

Love it great bike I have the baby mx100😁 great videos🙂👍

[@MitzvosGolem1]

Safer than a TM 400 cyclone monster. You gotta find one infamous TM Suzuki wobbly monster 70s KX 450 also cool.

[@mt1885]

The air-cooled sound of a 2 stroke

[@ronmangano9094]

Yes.It is fast. Mine is all original including tires. I also have a DT400B. I have a spare nos MX400B cylinder and head I've been wanting to try out on it. Will definitely make it hairier on the street!

[@EL-zo6iy]

Oh, AND riding ALL dream motorcycles, there is a god! Lol!

[@hectorpuertoricanrivera3470]

Awesome bike she moves out💪😎🇺🇲

[@20502chris]

I have an MX400B and I'm having the most difficult time looking for exhaust gaskets. Do I need them since it's like a slip on? The springs u have for the mid pipe seem too short and maybe something is supposed to be there?

[@eggswung6911]

That’s awesome

[@bobe3250]

Nice bike!!

[@donnywilcox3963]

Would this have been something Bob Hanna rode back in the day? ....I know he was a 500 guy ....just curious

[@donnywilcox3963]

@Tim Allen yeah I have watched a documentary on him and how he got started and his career ...saw footage of him on a 500 something like this ....just was wondering where this bike fit in ....bob tough dude won a moto go on a 125 he didn't want to ride ....broke his leg and almost lost it water skiing in a river with a rivel mx er and good friend .....then ended up flying and racing vintage fighter planes .... just seems like a really good guy and I guess one would say fearless......those old big bores were heavy and temperamental and he wasn't a huge guy ....mad respect for him ...

[@sayers_repairs]

Very nice bike. I had the 250. That is actually a Webco head though

[@swapmeetlus4096]

There’s one for sale locally, needs full restoration but it’s complete not seized and with paperwork, 1k or offer, is it worth it? I’m able to do almost everything mechanical wise

[@clarkpitts5393]

If you guys ever get the chance, could you maybe explain the difference between the various Yamaha models? What I mean is, what's the difference between and MX, YZ, DT and IT?

[@KaplanCycles]

Yes

[@reaper10]

@@KaplanCycles Sweet! I love the videos you guys do and really love the old Yamaha's you show. My first bike when I was 13 was a 79 DT175. I really miss it and eventually I'll get another one!

[@mrjolly8680]

Hi Kaplan, do you sometimes miss the mike toss, it’s super cool.

[@KaplanCycles]

Only once

[@MazzifLOL]

I just picked up a 75 MX400. Not nearly as nice as this, but still not bad. Seller though he had a 1979 IT400. But serial number tells me different (510 prefix).

[@andyg2119]

how much horsepower does it have?

[@larrynorsworthy8582]

Why did the mx and yz coexist or did they?

[@richardkrasicki6086]

The Monoshock that Yamaha used was designed by a Belgium Engineer, he was going to sell the design to Suzuki, but they did not want it, so Yamaha decided to go for it, and the rest is history..

[@MrGuvEuroman]

So is MX Pre YZ?

[@SteveHacker]

No... They co-existed... YZs started in 1974...

Nice bike but I don’t think your using the word “survivor” correctly.

[@vincepusey2157]

Had a dt 400 Mx I thought it would have more power I felt disappointed nothing wrong with the bike it just felt underpowered for me you’d think a 400 would have pulled the front up without slipping the clutch .

For Self Defense, have you watched the news lately?

[@sueneilson896]

@@KaplanCycles .. ru serious? Sorry, but I live in a country where nobody would dream of having to be armed. We have gun laws, and have much more freedom than you. Freedom from gun violence for a start. Feel sorry for you guys.

ALL the criminals have guns here, Not A-day goes by in America where in unarmed citizen is shot to death by a criminal with an illegal gun. In fact 2 weeks ago a very close friend of mine was walking out of a store somebody following him out and robbed him at gunpoint with a gun ... I am not a criminal. I have a licence for my gun and it is registered. Sometimes your best offense is a good defence.
