1975 Yamaha DT400B 

Such a cool old school Enduro Yamaha dirt bike, I remember seeing these as a little kid up in northern Michigan by our summer cabin and I thought they were the coolest thing as a little kid... and then the Cr the RM and the YZ 'S came out and change my opinion a little bit, Either way these are still very cool motorcycles lots of torque and Power and just a blast to ride, thanks for posting these videos brother it's so cool to relive a lot of these old school dirt bike memories via Kaplan motorcycles... you guys rock!!

That thing sounds so crisp. Minimal smoke. First time seeing it again since it left ma. Looks great. Good job Ken and team. / MOSES. Please give that bike my blessing.

Man that brings back memories.In 74 me my brother and couison all walked into a Yamaha dealer and told the sales guy we wanted 3 of those 400 enduros,he about droped this shorts.We road crap out of those bikes

Always love the dt series ❤❤❤

Lovely DT guys,good move updated to modern electronics these classic bikes really benefit it certainly transformed my RD250LC ,a lot of UK RD/DT owners are going down that route nowadays.

My late former BIL had one of those back in the day.

Sweet DT 400 Enduro! Stunning looking!

Those keys swinging so close to the side panel paint Seriously uncool I’m sure you didn’t mean it Ken I’m just finishing renovation on a low miles DT400B 1975 looking forward to riding it next summer. Another beautiful bike from kaolin cycles well done another classic bike saved for the future . I’d buy it in a heartbeat

1984 was the last year for the long steel tank on the DT AND AFTER THAT THEY WENT TO PLASTIC LIKE THE XR maybe it was to keep up on the new day and age stuff every one wanted . my 1973Dt 250 is steel my two 1977/1978DT 400 are steel then I got a 1975 orange tank white logos with silver fenders the same model of this one you guys got on this video got steel tanks my friend had a 1984DT 175 it was red the tank was not plastic then also so for what thinking 1984 was the last years of steel tank on any DT hope that helps

I didn’t know Wolverine did motorcycle builds in his spare time!.... 😜😂😜

My 1978 DT 100 had a metal tank.. man great job on the bike guys

Big 2 stroke brute!! Love it!

O man I had the 100 and my brother the 175 in the 70s rode them up in Adirondacks at my family’s cabin now he has the DR 650 and I have KLR 650 and 19 kX 450

I was wondering where you were going with all this detail but makes sense for a long second life

I have a 1978 with a steel tank yellow also but hasn't have the white on the tank and first moto shock also

Could always switch the pipe and cylinder head for IT..... it's such a skinny pipe but oh well great rig stock.

Can I ask who you send your engines to for rebuild? My local places don't want anything to do with old stuff they actually ignore me soon as I say 19_ if it's not in 2000s they push me away I really want to fix mx 75 dt250 engine wise rest I can figure out. I really appreciate it and wat beautiful bike wish I could just buy that instead but what fun is that lol I like seeing them come back to life!

I had one.

where would someone find a throttle cable for something like this

Sweet baby Jesus

Havent watched full vid yet is this the dt you use to drive around when you were young or was it a 125 mx,175 mx? Good vid BTW love all these old bikes

Good vídeos, weare tour from? I live Argentina , i have Yamaha DT 100 1979

I’m curious about the ignition system you guys used, is it one the Rex’s speed shop kits from the UK?

How do I even fuel the thing.

You could ride that one to California.

👌👌👌👌👌👌❤️❤️❤️

I got the same one it just sat for years it has no spark but me and compression

Nice purrs like a kitten

BUSY day for Kenny... ✔️

Would you be able to take this bike to and from work?

Hola amigo

these bikes are wierd to ride if ya ride newer 2 strokes as they don't really have a power bandn its just kind a raw power n very spongy forks lol

76 had metal tank

The best bike ever is Honda Magna.

Too bad this model of Motorcycle is out of my price range because this model of motorcycle is HOT but oh well I can keep dreaming though
