Kawasaki KZ1000 Drag Bike – Valtoron

Posted on July 12, 2014 by Andrew in Other. 24 comments


You’ve got to hand it to the Spanish. They are nothing if not risk takers. While America, Australia and England get their jollies from innocuous bat and ball sports, the Spanish get theirs taunting angry bulls. Now, I think it’s fair to say that the number of combined casualties for soccer, cricket and baseball players over the past few hundred years or so would be pretty much zero. Sure, there’s the cricket players that died of boredom and the soccer players that were just pretending to be dead, but overall they’re negligible. But compare that to bullfighting’s 533 deaths in the last 300 years. Serious stuff, but probably what you should expect if you jump into a ring with a beast like that. Or like this. Wave your red capes in honour of the nastiest, most powerful bull that’s ever lived, ‘La Bestia’ from Madrid’s Valtoron.


The Valtoron boys set out with the notion of building something that paid homage to the both classic drag bikes and those you’d see tearing across the salt flats at Bonneville while hunting for a land speed record to two. The name, as you can imagine, was pretty much the only choice for a 230hp, big bore, turbo drag bike. Except maybe ‘Diablo’.


The engine is about as subtle and a flaming sledgehammer to the teeth; there’s a Kawasaki Kz1000 with a Rajay F40 turbo force feeding it, a Kwaka big block 1327cc cylinder head and various MTC engineering components including their big bore piston kit, crank, cams and clutch. This was topped off with a special transmission, replete with an air shifter system. Something tells us these boys weren’t doing thing by halves.


On top of the fully modified frame sits a bespoke monocoque body, made in a single part from the tip of the fairing to the final, duck-tailed cowl piece. As the boys put it in their own, Madridian way, “Is the most time-spending part of the bike and obviously the most difficult part of the bike too.” We hear you.


The obvious, nay vicious rake on the forks was included as a means of increasing the beast’s wheelbase. Not only did this provide Valtoron with the stance they were after, but it also dramatically decreased the likelihood of wheelies, which is something that’s more than a little likely when you have 230 ponies on tap through your right wrist. The forks came off of a Yamaha FZR 600 and were shortened to suite. While a much more sophisticated front end could have been sourced, these ones were fitted because they filled the brief of being light, simple and reliable while being about to handle a lick of speed, too.


Not a weld or join in sight

The final touches on the bike were added using some rather elegant sand-cast pieces, including the turbo’s exhaust gate cover and the bike’s Mallory ignition belt guard. The parts were first fashioned in clay, and then used to make sand moulds into which the molten aluminium was gravity fed. We not only applaud the lads for trying such a different approach to their parts fabrication, but we also think that they are the beautiful focal points that really take the bike from good to great visually. And we love the typography, too.


Hand-cast parts, apparently made in 1327


If you, like us, are finding yourselves suddenly interested in bullfighting (especially the internal combustion variety), the you’ll be pleased to learn that Valtoron were kind enough to send us a muy español video featuring the bike which you can see here. Ole!


It’s a beast of a bike. No bull

    I love the way the fairings mated to the tank, but I thought you wanted bright lit pics? I really want to see whats under the tail area and how that part is all fabbed up but they hid it in shadows. My pics got denied for that same reason haha. Can we just enforce the pictures standards equally or are we picking favorites?

    • Andrew can pick favorites. It’s his site. Maybe your Goldwing isn’t his cup of tea. Please, stop whining about it. It’s getting really annoying.

      • Steve Joseph

        meh, I’m over it. I’m just here to look at the bikes.

        from a photography standpoint these pictures are awesome but as someone who builds bikes I am really curious to see the small fabrication details hidden in the shadows.

  • Chester

    That’s wicked.

  • Folke Bredkjær

    For me, this is beauty beyond comprehension. I wish only to hear it rawr.

  • TJ Martin

    Absolutely bat___ crazy and stunning . The video was well conceived and executed as well . But now could we please see a video of the bike being ridden in anger [ on the street or track ] rather than a moment of well done artistic expression ?

  • al gonz

    Amazing bike, amazing article!…but, VALTORÓN are from a small village in the middle of nowhere about 50 km from Madrid.

  • Juan Francisco Ramirez Fernand

    Madrid’ Valtoron…….MADRID!!!!

  • SO nice. I’m with TJ Martin. A video that really showcases the raw power of this thing, rather than artfully alluding to it would be nice

  • MayDayMoto

    The body work is spectacular. Looks like it might be a tribute to Shinya’s “Spike” dragster, which he regularly rides in Bonneville.

  • Bryan White

    Love the craftsmanship on the bodywork and the hand-cast parts. Oh by the way, the “1327” on the exhaust heat shield refers to the bike’s displacement 🙂

    • No, really!? 😉

      • Bryan White

        Figured it was tongue-in-cheek!

    Why all these pictures in the dark?
    Will someone please proof-read the stories before they go live?

    • Seth,

      We ALWAYS proofread before the stories before they go live. Have you spotted we missed? I just had a quick look now and I can’t see anything…


      • sethasaurus

        Not to be too picky, but:
        “paid homage to the both …”, should be “paid homage to both the …”

        Also, the forks were “shortened to suite” (should be ‘shortened to suit”).

        And it’s debatable, but “there’s the cricket players” should be “there are the cricket players” (even though “there’re” is technically correct, we do not often write it and it does not pass a spellcheck)

        Of course it’s no big deal. I read pipeburn because it’s interesting and well-written anyway. Minor mistakes are forgivable – it’s just that, your brain is taught to trust the information coming from a literate source as sensible and correct, then out of the blue, it gets a ‘suite’ when it expects a ‘suit’, and it does a bit of a double-take.

        Certainly better than an article I read in a major newspaper about a man who fabricated a set of replacement stainless steel teeth, and was reported to have “no problems with them when eating and kissing his wife”…

    Well.. now that you mention it.
    Text correction suggestions.
    ..while hunting for a land speed record to two. Should be “or” two.
    ..piston kit, crank, cams and clutch. (missing comma after cams)
    ..The engine is about as subtle and a flaming… Should be “as” a flaming…
    ..ref: FZR forks, these ones.. OUCH! loose the “ones”
    ..simple and reliable.. (missing comma again).
    ..while being about to handle a lick of speed.. (should be “able” to handle a lick of speed, too. (No comma needed after speed)
    Sorry, cool bike though.

      Nothing worse than grammar police who are wrong. Thank you Andrew for not changing the article and keep up the good work. I think everyone will agree the last thing people want to read in the comments is someone’s opinion of whether they believe the grammar was acceptable.

  • Axel

    Beautiful! I am stunned. The bodywork is very “Britten” especialy the headlight. Beautiful bike, fantastic craftsmanship.
