1977 Honda CT70 Dax

Posted on August 21, 2011 by Andrew in Classic, Other. 51 comments

Customising a bike is in many ways a truly epic undertaking. It’s like the Everest climb of the mechanical world, requiring equal parts engineering skills, design, creativity, problem solving, patience and brute force. So now imagine we tell you the story of a man who climbed his own personal motorbike Everest, but decided to do it walking backwards, naked, while carrying his mother-in-law on his back. That’s about the size of the challenge that Texan Dave Morales undertook when he committed to customising what could easily be the world’s most uncustomised bike. No pre-fab parts or extensive online repositories of information for this intrepid explorer, no sir. A mission of this magnitude is tantamount to going when no man has gone before. And now that we gaze admirably upon his creation, we think it’s fair to say that what he has achieved is much more than one big step for Dave, but it’s also one giant leap for biker-kind. Houston, we have a custom…

“My name is David Morales. I live in Denton, Texas, about 30 miles north of Dallas. Customizing bikes is something I’ve gotten into the last few years, with a background in all sorts of metal work from jewelry to hotrod autos, to boutique electronics. The 1977 CT70 or Dax bike was one of two given to me for restoration of a Honda SL70 done for a friend. The bike was little more than a roller, with a worn out 1970 CT70 H engine, and many missing parts. The engine ended up in a restored 1971 CT70. The frame sat on the floor of the shop under a table, and I tried to give it away at some point, but no takers.”

“Most of the custom bikes I have made start with less than perfect frames, that are never going to be good enough for a complete stock restoration, or are less desirable because of the year model. While this frame was not defective, there isn’t much interest in the particular year. There was no finished bike in mind at the start, but a stripped-down cafe somehow got stuck in my mind. Not just because I had not seen it attempted, but because it was such an unlikely candidate. I would hardly call the end result stripped down, probably could have done less chrome, but oh well…”

“I started the project making the clubman style front bars from 1969 Z50A and 1973 SL70 handlebar pieces. The front end was lowered 30cm by way of a newly fabricated top clamp made from two original style ones. This also gave a significant amount of preload on the front shocks, and reduced travel. These bikes were made for off-roading by children and have notoriously soft suspensions. A fork cross brace was also fabricated to tighten up the front end. The handlebar mount is kind of interesting in that is the lower portion of a triple tree brace, turned around. This allows the whole handlebar assembly to slide up or down on the forks. It also further tightens the front forks.”

“The body was modified extensively, with thin plates of metal added outside to smooth the usually stepped lower portion of the frame, and interior boxing and cross bracing. Aluminum torque plates were fabricated for the lower body where the engine and rear fork mate with the frame. These Dax frames are made with fairly light gauge metal, with a lot of body flexing as a result. To try and compensate further in the rear suspension, the top shock mount was redesigned to lower it 30cm, with a two bolt shackle to replace the normal single unshackled ones. This also allowed shorter 280mm shocks to be used, limiting travel. An interior cross brace was fabricated between the upper shock mounts. There is an all but hidden brace that runs from the rear engine mount to the tail of the frame. Even the seat is used to brace the rear portion of the frame, with solid steel members anchored securely at both ends.”

“The engine is a CRF70 lower case with a stroker crank and new piston and head for 117cc’s. The intake manifold, carb and intake boot are from a 1966 CT90, one of few Honda/Keihin downdraft carbs. The velocity stack is a Webber, with a grill made from a portion of a crock-pot assembly. The engine cradle and rear peg mounts are one solid piece, made of steel. The rear fork and shocks are from Kitaco. Michelin tires. The exhaust was fashioned from a Norton 850 commando pipe with a modified 1969 Z50 canister, and CT90 heat shields. A number of parts were fabricated from aluminum billet for this project. I did all the fabrication on this project, all body and paint, everything but the chrome plating and sewing of the seat cover.”

“This bike is a blast to ride, as quick as any small bike should be, and EVERYONE has a Dax story from their youth to tell you when they see it. I have only put a limited amount of miles on since final completion, most of the miles on this thing were during the shake-down. And I’m glad to say I have had a lot of positive responses to the bike.”

So next time you are lying in bed cursing your “bad luck” when the mass-produced rear-sets you ordered from eBay are running a whole 24 hours late, spare a thought for the pioneers. The wild ones, the ones who tread the road less travelled – or as we will call them from now on, the “Dax” men.

Update: we have video!

    Like it or hate it, but it is original. I like stuff like this, it is creative, who would ever imagined that we would see something like this come from anyone but a 15 year old in Hong Kong? The CT70 was just coming out when I was about to turn 16 so I never had one, but I think just about every other kid in existence started out on one in the US. Congradulations, this is what a custom is all about!!

  • HAZ

    I think it's badass! Customized bikes are about expression. You don't have to like it. You don't have to ride it. As long as they are wrenching and they are riding, I'm good with it.

  • Justin Stroud

    Very cool little bike!

  • SmokeyTheBear

    I wanna see what he looks like riding it.

  • Jay Allen

    Lots of hard work anyone can see, and everyone should appreciate

  • Assholewelder

    He is no pioneer!!!. try and google honda dax, And you will see a lot of tuned and customized honda dax. He might have made at nice dax, but he hasnt carried a Mother in law over the Everest…………

  • Assholewelder

    Even at age 13, this bike seemed too small for me, is Dave Morales a midget???

  • My Mother-in-law now wants me to carry her over Mount Everest- dang you Texas Dax-master!

  • davmo

    Thank you for all the kind compliments, even the back handed ones. To answer AHW above, yes, I am a midget, but here in Texas that translates to about 5'10". Thanks to Andrew and Scott for all they do.

  • zeke rigg

    not the first or even in the first wave of customs for these things. none the less a sweet bike worthy of being posted on pipe burn. did i mention it was sweet yet?
    also hows it run with the stroker crank and bigger head and which ones did you use? i am running a 88cc kit on mine and a 20mm clone carb. does the head help much?

  • trackfiend

    That is an awesome little bike! The out of the ordinary builds are always inspirational to me since I am building something that's not a main stream cafe bike as well. Glad to see there are such talented builders that are near where I live. The details are top notch man.

  • Foundation982

    I want a video!

  • Ash Bali

    Perfect choice of handlebars to 'lengthen' the reach. These things have a cult following in places as unlikely as Denmark. This one is a really good quality build. I thought everything was big in Texas?

  • rdjmp

    Hey neighbor…. Great to see one of your cool machines here!

    I live near David and it's always interesting to hear one of his restorations or customs zooming up the street and wondering what's going to appear. The guy absolutely epitomizes the spirit of old-school custom craftsman – grinding, hammering and welding truly unique stuff from nothing but iron, aluminum and imagination.

  • Andrew

    We have video! See above. 🙂

  • Dax

    Nice bike, does anybody know where the name Dax came from in relation to this bike? This happens to be my name and I'm just curious. Keep up the great work Pipeburn!

  • davmo

    Hey Dax, As far as the name "Dax," in Japan, the bike is known as the "Dachshund." This is perhaps a reference to the similarity between the body, and a German wiener dog. Dax is just the shortened version.

  • Dax

    Thanks Davmo.

  • rubbersoul1991

    sounds like it desperately needs a tune. looks good tho

  • davmo

    Hey Rubbersoul, thanks for the concern, but bike is tuned just fine. Can't tell too much with compressed youtube audio. Promise you, this one rips, couldn't really let it rev too much in my 25 MPH neighborhood. Can't tell from video, but this thing is plenty loud. Noticed that one of the replies to Zeke went unanswered, sorry about that. The head makes a big difference over the stock one. The stroker crank
    delivers on the torque as advertised. The 88cc bore-ups I've done in the past that use the Hondatrailbikes head noticeably outperform the stock ones. Hope that helps. Once again, thank you for all the helpful comments.

  • Cool

    only thing i’d change is running moped clip-ons (which are cheap and readily available in a number of sizes)…then the bike would be perfect.

  • Ruezi

    Your interpretation of the Dax ist absolut great!!! There is so much detail work in this project. Congratulation to this bike.
    Best regards
    Rüdiger from Austria

    • Davmo

      Thanks, Rudiger. It was a lot of fun working on this one, it is still one of my favorites. 

    • Humphries S

      Dave ….make me one please…..seriously…..could you??

  • Davmo

    Would love to. Give me an email and we can talk. davidmorales1

  • Matski skoy


  • Autolux

    Your email does not seem to work…I too have that same question?

  • davmo  it would seem that the above address has an error, and I am not sure how to edit it. Sorry about the trouble.

  • Jamie

    I really like the looks of the swing arm you chose to use, can you tell me where I can get one?
    pretty please 😀

    • davmo

      Hey Jamie, It is a kitaco+10cm swingarm. They are available from a number of sources, but I got it at Classic Honda Parts in Longview, Tx. (CHPminis)

  • ShapeShifter

    Hey look at this. I found Davmo over here on a site where real motorcycles are built. As it should be.

    • davmo

      DUDE! You found my second favorite site (or is it third? well, no matter…) Good to see you getting outside the mini zone. Now go back to PM, and let the big boys play with their bikes.

  • americandolt

    Work of Art!

    • davmo

      Thanks, man. I have a really crazy Z50 hardtail that is just about complete. Maybe it will show up here.

      • Kapistijn

        really really love your work. I myself fancy working on gorilla z90. But what you did here is mind blowing, nice one. did you weld the ot handlebars your self? Really really love this machine. the eye for detail is stunning. Congrats on this beauty

        • davmo

          Yes, the bars were welded from pieces of two other bars (1973 Honda SL70 for the center portion, and 1969 Z50 for the rest.) The handlebars started the process. It was July of 2008, and I had these extra bar parts from another build, and built them thinking that was going to be all, but as you can see, it just kept going. Thank you for the kind words.

  • Gaelicfonz

    Hey how u doen just wondering ,have u any drawings or ideas wear i can get a seat like this.
    This bike is a real gem but the seat design is awsome and would love to incoperate it in my project bike

    • davmo

      The only template I kept was for the seat pan, would be happy to share it. Thanks for the kind words.

      • ToeKnee Tee

        Hey man .. would love to get that template from you .. this seat is titties!!! looks like you modified the stock hinge as well?

  • Jiggyfly

    Lets not kid ourselves…….there are mountains of aftermarket parts for CT70’s.
    I’m not suggesting this one isn’t unique, or custom……but there’s boatloads of custom CT70’s.

    • FloppyDisk

      Most of the boatloads of “custom” CT70s I have seen in pictures and in person are assembled from catalog parts. Very few have as many hand-crafted parts as this bike does.

  • phill

    I got a 1971 Honda ct 70, but who knew a bike like mine could turn out like this.

  • danny Sullivan

    I had one of these. Used to race it on a homemade track in a cornfield.

  • gonzalo macedo

    Hola David, el estilo de tu moto me encanta, pienso comprarme una dax y al ver tu modelo tengo mas ganas de hacerlo, quisiera si es posible que me ayudes porque quisiera que quede parecida si no es problema, me puedes decir algunos datos de como puedo hacer que quede asi la mia.
    gracias por tu respuesta.

  • Kyle

    Would you be interested in fabricating a similar seat for a 74? I love the design and speak look, as you would imagine I can’t find any unique Cafe style seats online for the bike.

  • mtnsicl

    How could you not like this little bike? Well done!!
